Description

Technical Field

[0001] This utility model relates to the technical field of motor stator processing equipment, and in particular to a fully automatic straight stator winding line. Background Technology

[0002] Straight stators are core components of linear motors, frameless torque motors, and other products. Their production process includes multiple steps such as winding, terminal crimping, and trimming of excess wire. Currently, straight stator processing in the industry mostly uses separate, single-machine equipment. After the winding process is completed, the workpiece needs to be manually transferred to the terminal crimping equipment for subsequent processing. The loading and return processes also heavily rely on manual operation, resulting in low production efficiency, high labor costs, and poor product consistency and unstable yield due to positioning deviations caused by manual handling.

[0003] Meanwhile, for long straight stators, the number of terminals is large and the distribution span is wide. Single-station terminal pressing equipment needs to move the workpiece or processing head repeatedly, resulting in a long processing cycle. This makes it difficult to match the production rhythm of the winding process and prevents the formation of a continuous automatic production line, thus restricting the large-scale production efficiency of straight stators.
