Welding mask for live teaching

Abstract

The invention relates to a welding mask for live teaching and belongs to the technical field of welding masks. The welding mask comprises a welding mask body, a display assembly is arranged at an observation window of the welding mask body and is in electric signal connection with external display equipment through a wireless transmission line set. The display assembly comprises a control panel and a camera shooting plate tightly attached to the inner side of the control panel, a liquid crystal piece assembly is arranged in the control panel and sequentially comprises an outer protection piece, an anti-red and anti-ultraviolet lens, a liquid crystal piece, a liquid crystal piece protection piece and an inner protection piece from outside to inside, and a wireless camera is installed on the camera shooting plate. The display assembly is arranged, the welding position watched by a welding operation teacher in the view field can be focused and changed along with change of the view field, the welding operation process is transmitted into the display equipment, a real-time live broadcast picture is provided, detailed operation in the welding process can be displayed from the first view angle, and students can conveniently observe and learn the situation.

Description

technical field [0001] The invention belongs to the technical field of welding masks, and in particular relates to a welding mask used for live teaching. Background technique [0002] In the process of manual welding teaching or training, the traditional teaching mode is that the teacher demonstrates on the console and the students observe around the console. However, there are often a large number of students, and not every student can intuitively see the teacher's operation, and Due to the interference of strong light and smoke, it is difficult for students to clearly see the changes in the shape of the molten pool and the teacher's subtle movements such as gunning and twisting. [0003] The problem with the existing welding masks for teaching is that only a remote screen is given to the students to watch, and the positioning of the teacher's eyes and the details of the teacher's attention to welding have not been well displayed.

[0002] In the process of manual welding teaching or training, the traditional teaching mode is that the teacher demonstrates on the console and the students observe around the console. However, there are often a large number of students, and not every student can intuitively see the teacher's operation, and Due to the interference of strong light and smoke, it is difficult for students to clearly see the changes in the shape of the molten pool and the teacher's subtle movements such as gunning and twisting

[0003] The problem with the existing welding masks for teaching is that only a remote screen is given to the students to watch, and the positioning of the teacher's eyes and the details of the teacher's attention to welding have not been well displayed. At the same time, it is only a fixed position. The viewing angle of view does not reflect the viewing angles of different angles during welding

At the same time, the emergence of AR technology makes virtual manual welding possible, but the virtual technology of VR completes all operations by pressing a handle. In the existing technology, the virtual technology shows scenes that are artificially edited in advance. , no consideration is given to the situation encountered in actual welding
