AI Technical Summary
Technical Problem
In existing robotic sewing technology, due to the fixed lower arm column, it is difficult to effectively sew parts with complex geometries, often resulting in problems such as the sewing head colliding with or failing to make contact with the parts.
Method used
It adopts a rotatable lower arm design, which is driven by a motor to rotate around a horizontal axis. Combined with a transmission system and a programmable control system, it can maintain the position of the needle plate and butterfly looper and adapt to complex component geometries.
Benefits of technology
It enables the sewing of complex 3D planar parts, enhances the adaptability and flexibility of the sewing head, avoids collisions between the sewing head and the parts, and improves sewing efficiency.

Abstract
The robot sewing assembly comprises a sewing head body, an upper arm, a motor and a lower arm. The upper arm is connectable to the sewing head body and includes a sewing needle oriented along a first axis. The lower arm is rotatably connected to the sewing head body so as to be rotatable about a second axis transversely defined by the motor relative to the first axis. The lower arm comprises a needle plate, a butterfly curved needle, a first transmission system and a second transmission system. The first transmission system may extend through the lower arm and is configured to maintain a position of the needle plate during rotation of the lower arm. The second transmission system may extend through the lower arm and is configured to drive the butterfly curved needle during rotation of the lower arm.
