Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic line folding machine. BACKGROUND

[0002] At present, the stator assembly in the flat wire motor includes a stator core and a stator winding, the stator winding is formed by flat copper wires inserted into the stator core, the flat copper wires will form a flat wire end and an extended wire at the end of the stator assembly after being inserted into the stator core, the extended wire is used for welding three-phase terminals, and the length of the extended wire is greater than that of the flat wire end, so the extended wire will protrude upward. In the subsequent processing procedure, the stator assembly needs to be twisted in the head twisting device, and the flat wire end also needs to be cut flat in the head cutting device, and then the cut flat flat wire end is welded together. The full-automatic head twisting device disclosed in Chinese patent CN118337004A can be used for the head twisting of the flat wire end, and the hairpin type stator head cutting device disclosed in Chinese patent CN219554770U can be used for the head cutting of the flat wire end.

[0003] However, due to the long length of the extended wire, the extended wire protrudes upward, and when the stator assembly is twisted in the head twisting device and when the stator assembly is cut in the head cutting device, the extended wire will interfere with the head twisting device and the head cutting device, resulting in abnormal processing. The current solution is to manually bend the extended wire to avoid interference with the head twisting device and the head cutting device, but manual bending not only has low efficiency but also increases labor costs.
