Abstract

The invention discloses a single-layer form-wound coil winding device which comprises a pay-off frame, a guide frame and a winding machine which are sequentially arranged; the winding machine comprises a horizontal rotating platform, the center of the bottom of the rotating platform is provided with a vertical rotating electric machine for driving the rotating platform to rotate horizontally at any angle in the clockwise or counterclockwise direction, and a horizontal swinging mechanism is arranged along the diameter of the top surface of the rotating platform above the rotating platform; the top surface of the swinging mechanism can be provided with a winding mold for winding a single-layer form-wound coil, wherein the axial direction of the winding mold is parallel to the axial direction of the swinging mechanism; and the pay-off frame is provided with a pay-off reel; the guide frame is provided with a clamping roller frame, and the clamping roller frame is provided with a pair of horizontal clamping rollers. The technical effect is that the device can integrate equipment to a greater extent and save the manufacturing cost. The single-layer form-wound coil can be directly wound through the turn-by-turn angled winding process, which can effectively prevent the corner bending of the end portion from rebounding and the inter-turn insulation damage. The invention also discloses a single-layer form-wound coil winding method.

Description

technical field [0001] The invention relates to a single-layer forming coil winding device and winding method in the field of motor manufacturing. Background technique [0002] At present, single-layer forming coils are divided into three specifications according to the bending angle of the end: 0 degree coil, 45 degree line segment and 90 degree coil. The three kinds of single layer coils are manufactured by equipment with different manufacturing principles. The 0-degree coil adopts direct flat winding; the 90-degree coil adopts two-axis switching winding or first flat winding and then bending; the 45-degree coil is first flat winding and then overall bending treatment. [0003] The single-layer formed coil manufactured by this method is not only difficult to control the amount of springback after bending, but also prone to inter-turn insulation damage during bending, and the lack of versatility of equipment leads to high manufacturing costs.
