Description

Technical Field

[0001] This utility model relates to the field of automatic welding technology for automotive sensors, and in particular to a flip welding fixture. Background Technology

[0002] In recent years, China's automotive industry has developed rapidly, with output increasing year after year. This has placed a heavy burden on equipment and manpower. Many companies have tried to increase production capacity by adding equipment and manpower to solve production bottlenecks and cycle times, resulting in huge wastes of space, energy, and manpower. Increasing production capacity, reducing production cycle times, improving production efficiency, and saving production space have become the primary factors in production. In the production of automotive sensors, various parts often need to be pre-assembled before welding. However, existing welding equipment mostly uses six-axis robotic arms for flexible 90° flip welding and one-point welding by the robotic arms. This method has low production efficiency, easily leads to a large backlog of semi-finished products, and also causes problems such as difficulty in handling parts, large space occupation, high equipment investment costs, and high energy consumption.
