[0002] The flat wire stator of the flat wire motor includes a flat enameled wire and an iron core. The enameled wire is formed and wound into the core slot on the iron core. The spacing between the welding ends of the enameled wire affects the creepage distance. Therefore, before welding the enameled wire, it is necessary to clamp and position the welding ends of multiple enameled wires to ensure their spacing; but since the welding ends of multiple enameled wires along the radial direction of the iron core will fit together after assembly, it is not easy to clamp and position the welding ends of multiple enameled wires. Since the enameled wire is thick and has low flexibility, it is difficult to separate them manually and the speed is slow. In order to increase the production speed, an enameled wire separation device is proposed to perform preliminary separation of multiple enameled wire welding ends before positioning.

[0027] The enameled wire separation device according to the embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-Figure 3As shown, the enameled wire separation device according to the embodiment of the utility model includes: a support part 1, a second drawing part and a first drawing part; the support part 1 is used to place the iron core 61, and the support part 1 can drive the iron core 61 to rotate around the central axis of the iron core 61, the second drawing part is located on one side of the support part 1, and a guide block 21 is provided on the first drawing part, and the guide block 21 is formed with a socket 211 along the central axis direction of the iron core 61, and the socket 211 passes through the guide block 21, and the socket 211 is used to socket the enameled wire welding end 62, and the first drawing part is used to drive the socket 211 to reciprocate along the central axis direction of the iron core 61 to drive the socket 211 to socket or leave the enameled wire welding end 62, and the first drawing part is arranged on the second drawing part, and the second drawing part is used to drive the first drawing part to reciprocate along the radial direction of the iron core 61 to drive the enameled wire welding end 62 to bend a certain distance along the radial direction of the iron core 61.

[0029] In this embodiment, the iron core 61 is placed on the support part 1, and the second drawing part drives the first drawing part to move horizontally until the socket 211 is located above the enameled wire welding end 62, and then the first drawing part is pushed down, so that the first drawing part drives the socket 211 to be sleeved on the enameled wire welding end 62 and close to the iron core 61. At this time, the first drawing part is driven away from the iron core 61 by the second drawing part, and the enameled wire welding end 62 is stretched horizontally under the action of the socket 211, so that the enameled wire welding end 62 is bent, and then the first drawing part drives the socket 211 to move upward, so that the socket 211 leaves the enameled wire welding end 62. In this process, since the path of the socket 211 is vertically upward, the enameled wire welding end 62 extends vertically upward after bending to complete the shaping; then the second drawing part is pushed so that the socket 211 is located at the enameled wire welding end 62, above the enameled wire welding ends 62 adjacent to each other in the transverse direction, push the first drawing part downward so that the socket 211 is socketed on the enameled wire welding end 62 below it, so as to complete the shaping of the enameled wire welding ends 62 adjacent to each other in the transverse direction by using the above steps, so that a certain distance is pulled between the two adjacent enameled wire welding ends 62 in the transverse direction, so as to facilitate the positioning of the enameled wire welding ends 62 in the transverse direction during subsequent welding; after the enameled wire welding ends 62 in the same transverse direction are shaped, rotate the support part 1 so that the adjacent enameled wire welding ends 62 along the circumferential direction of the iron core 61 are located below the socket 211, and continue to complete the separation between the enameled wire welding ends 62 by the above steps, apply force to the enameled wire welding ends 62 through the socket 211, and use the first drawing part and the second drawing part for guidance, thereby saving manpower and improving the production speed.

The through hole and the socket 211 are arranged side by side along the radial direction of the iron core 61, and the through hole is long and strip-shaped along the radial direction of the iron core 61. The through hole is used to provide space for the remaining enameled wire welding ends 62 in the same radial direction when the socket 211 performs shaping operation on the enameled wire welding end 62, so as to avoid interference of the remaining enameled wire welding ends 62 with the guide block 21.

[0038] One end of the slide plate 32 away from the support portion 1 is connected to a traction portion 5 , and the traction portion 5 is used to pull the slide plate 32 to perform linear reciprocating movement.

[0039] In this embodiment, the traction portion 5 has a guiding function and can pull the slide plate 32 to move linearly along the setting direction of the first guide rail 311 .
