Description

Technical Field

[0001] The utility model relates to the technical field of stator manufacturing, in particular to an integrated wire-inserting tooth guard plate for a stator. Background Technique

[0002] A stator is a stationary part of a motor or a generator, and mainly consists of a stator core and coils wound around the stator core. In a stator processing production line, the stator needs to go through processes such as paper insertion, wire winding, wire insertion, shaping, and wire tying.

[0003] Currently, the general wire-inserting method for a stator is as follows: A robot grips the stator and feeds it to a wire-inserting die. The wire-inserting die positions the lower end of the stator. The pressing mechanism above the wire-inserting die descends to press and position the upper end of the stator. Finally, the pushing structure on the wire-inserting die embeds the wire into the stator. Generally, the upper tooth guard plate for wire insertion is arranged on the pressing mechanism, and the lower tooth guard plate is arranged on the wire-inserting die. The two are separately arranged. During wire insertion, the upper and lower tooth guard plates need to move relatively and dock, which requires multiple positionings, with cumbersome operations and a complex structure, thus affecting production efficiency.
