Description
Technical Field

[0002] A chair is a piece of everyday furniture, a seat with a backrest and armrests. Nowadays, chair styles are incredibly diverse, including office chairs, rocking chairs, and folding chairs. Most office chairs today are assembled from two parts: a metal frame and other materials. Manufacturing the metal frame is complex and costly due to its varied shapes and large size, making a single molding process expensive and difficult; therefore, welding and assembly are often necessary. With technological advancements, robotic arms are increasingly used for welding in manufacturing. However, robotic welding requires extremely precise fixtures with minimal error. Unlike traditional welding fixtures, it demands precise fixation of components. Using ordinary welding fixtures can easily lead to misalignment or displacement during welding, affecting the quality of the final chair and creating safety hazards.
