Description

TECHNICAL FIELD The present invention relates to a stator winding device for winding a stator of a motor.

"Prior Art and its Problems" A stator used in a fan motor or the like has internal teeth that protrude inside, and a wire is wound around the outer circumference of the internal hot water. Various devices for winding wires on a stator are known. Generally, a guide jig called a former is inserted into the stator, and the wire is guided by a needle shaft that partially rotates back and forth while discharging wire from its tip. The wire is wound around a jig, and the wire is guided by a guide jig while being wound around the internal teeth protruding inside the stator.

However, in such conventional winding devices, operations such as introducing and unloading the stator into the device main body were often performed manually. In addition, since the ends of the coils of the stator that have been zero-wired remain cut, their directions are inconsistent, resulting in poor workability when conducting continuity tests and the like in subsequent steps. Furthermore, if the end of the coil remains cut, the winding often becomes loose before being fixed to the terminal in a later process.

Since the stator is introduced into the winding device main body through the plate in this way, the installation and other handling of the stator is relatively easy, and the introduction of the stator can be automated. In addition, after the winding is completed, the end of the coil can be held by pressing it against the holding part of the plate, making it easier to conduct continuity tests in later steps, and
It is possible to prevent the coil from loosening until the end of the coil is fixed to the terminal part.

A reversing device 42 shown in FIG. 3 turns the plate 20 upside down when it is installed on the table 64 of the winding device main body 81. As described above, when the winding is completed, the end of the coil is in contact with the base 35 of the plate 20. In this state, when the cylinder S9 is actuated to move the movable rod 95 upward, the holding member 9B attached to the upper end of the movable rod 85 is pressed against the plate 20 so as to sandwich the ball 34 of the holding portion 37. At this time, the coil ends are also pressed together and held between the balls 34. Therefore, the end of the coil can be held at a predetermined location on the plate 20, making it easier to perform subsequent processes such as continuity testing. Further, it is possible to prevent the winding from loosening before the end of the coil is fixed to the terminal in a later step.
