Description

Technical Field

[0001] The invention relates to the technical field of welding machines, and in particular to a welding machine with an adjustable corner welding positioning structure. Background Art

[0002] A welding machine is a device used to connect two or more metal or thermoplastic parts together. Welding machines can be divided into arc welding machines, resistance welding machines, laser welding machines, and ultrasonic welding machines. Among them, laser welding machines use high-energy-density laser beams as heat sources for welding. Laser is a strong light with good monochromaticity, coherence, and directionality. When the laser beam is focused on a tiny area on the surface of the weld, the light energy is absorbed by the material and converted into heat energy, causing the material to melt or even vaporize rapidly. During the laser welding process, the melting of the material mainly occurs in the area irradiated by the laser spot. It is widely used in the electronics industry, precision machining and other fields. In the production of electronic equipment, it is used to weld tiny electronic components and circuit boards because it can achieve high-precision welding, with a small welding heat-affected zone, and will not damage the surrounding sensitive components. Existing welding machines usually use a manipulator to adjust the welding position and angle of the welding head, but the manipulator is prone to loosening after long-term use and is difficult to detect in time, resulting in a slight deviation of the welding position and angle, affecting the welding effect.
