Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and in particular to a welding robot based on vision recognition. Background Technology

[0002] In modern industrial production, welding is a crucial process. Traditional welding methods rely heavily on manual operation, which is not only labor-intensive and inefficient, but also significantly affects welding quality due to the worker's skill level and working condition, making it difficult to guarantee consistent and stable welding quality.

[0003] With the continuous advancement of technology, welding robots are increasingly being applied in industrial production, greatly improving welding efficiency and quality. However, existing welding robots cannot provide real-time image feedback on the welding points during the welding process, resulting in an inability to control the welding quality. In addition, the strong light and smoke generated during the welding process can affect and interfere with the information acquisition of the camera and the video quality of the welding.
