Description

Technical Field

[0001] The invention relates to the technical field of steering wheel processing, in particular to an automatic feeding tool for a steering wheel steel rim. Background Art

[0002] In the manufacturing process of steering wheel rims, loading is a key step to connect raw materials with subsequent processing procedures. Traditional loading methods rely on manual operation or semi-automatic mechanical equipment. Workers need to manually carry the steering wheel rims from the storage area to the processing mold, which is not only labor-intensive but also inefficient. In addition, manual loading also has problems such as inaccurate positioning and easy damage to products, which seriously affects product quality and the overall efficiency of the production line. Semi-automatic loading is assisted by simple robotic arms to complete the handling. These robotic arms usually move along preset trajectories and have limited flexibility.
