Description

Description: TECHNICAL FIELD The present invention relates to a stator transport plate used for introducing a stator into a winding device body and carrying it out when winding a stator of a motor.

“Prior Art and Problems Thereof” A stator used for a fan motor or the like has internal teeth protruding inside, and a winding is made around the outer circumference of the internal teeth. Various winding devices for such a stator are known. Generally, a guide jig called a former is inserted into the stator, and a guide is provided by a needle shaft that partially reciprocates while discharging a wire from the tip. While winding on the jig and guiding the wire with the guide jig,
The inner teeth protruding inside the stator are wound.

However, in such a conventional winding device, work such as introduction of the stator to the main body of the device or unloading of the stator is often performed manually. Further, since the wound coil ends of the stator are still in the cut state, the directions are different and the workability is poor when conducting a continuity test in a later process. Furthermore, if the coil ends are left cut, the windings are often loosened before being fixed to the terminals in a later step.

"Object of the Invention" An object of the present invention is to introduce a stator into a winding device body,

Each coil end pressing device 94 has a movable rod 95, a U-shaped pressing member 96 is attached to the upper end of the movable rod 95, and the lower part of the movable rod 95 is wound with a winding device main body 61 by links 97 and 98. It is supported on the lower part of the body so that it can swing vertically. Here, the link 97 is formed in an L shape, and one end thereof is pivotally attached to the lower part of the movable rod 95,
The middle part is pivotally attached to the main body 61 of the winding device, and the other end is pivotally attached to the tip of the cylinder 99. The rear end of the cylinder 99 is pivotally attached to a support member 100 extending to the lower part of the winding device body 61. Therefore, the movable rod 95 moves up and down by the operation of the cylinder 99.

By the reversing device 42 shown in FIG. 3, the carrying plate 20 is turned upside down when installed on the table 64 of the winding device body 61. Then, as described above, when the winding is completed, the coil end portion is in contact with the table 35 of the transport plate 20. In this state, when the cylinder 99 is operated and the movable rod 95 is moved upward, the pressing member 96 attached to the upper end of the movable rod 95 is pressed against the transport plate 20 so as to sandwich the ball 34 of the holding portion 37. At that time, the coil ends are also pressed together, and the coil ends are sandwiched and held between the balls 34. In this way, since the coil ends are held at the predetermined positions of the plate 20, the work can be facilitated in the subsequent steps such as the continuity test.
Further, it is possible to prevent the winding from loosening until the coil end is fixed to the terminal in a later step.

Along with this, the male member 82 and the female member 83 are vertically separated from each other (see FIG. 4). Further, the cylinders 76, 76 are actuated to raise the table 64 and lift the transport plate 20 to a predetermined height. The arms 51, 51 of the rotating device 43 hold the carrying plate 20 and the rotating shaft 47 rotates 180 ° (third part).
See figure). Then, the transfer plate 20 is placed in the reversing device 42.
The arms 45, 45 are held, and the arms 51, 51 are opened with it, and the transfer plate 20 is passed to the reversing device 42. Further, the rotating shaft 44 of the reversing device 42 rotates 180 °, and the mounting surface of the stator 12 of the carrying plate 20 faces upward. In this state, the elevating device 41 rises to support the transfer plate 20 and the arms 45, 45 of the reversing device 42 open, so that the transfer plate 20
20 is installed on the lifting device 41. The elevating device 41 descends again to install the transport plate 20 on the chain conveyor 19,
The transport plate 20 is transported to the next step by the chain conveyor 19.
