Traditional manual assembly methods have problems such as low efficiency, low precision, and poor consistency, making it difficult to meet the needs of large-scale, high-quality production. The development of industrial automation has prompted enterprises to seek more efficient and precise assembly solutions, and high-precision industrial assembly robotic arms have emerged.
