Embodiment approach

[0047] The slope end 27 of the plane cam 29 has a lowest point and a highest point. According to the first embodiment of the present invention, when the winding device is in the initial position, the ball 26 can contact the lowest point of the slope end 27, when the stator When the pawls of the claws have finished winding one layer, the highest point of the plane cam 29 is just in contact with the ball 26. During this process, since the plane cam 29 and the positioning gear 14 only rotate without axial movement, the ball 26 is on the plane cam. Drive the sliding support block 9 to move along the slide bar 8 under the action of the sliding support block 9 and the lifting frame 17, and the winding unit is fixed on the lifting frame 17, so the winding unit will move along with the lifting frame 17 as a whole, here In the process, the winding needle 25 just winds up one deck of the stator claw. Now, the winding motor 18 continues to rotate, and at this moment, the lowest point on ...

Abstract

The invention provides a winding device. The device comprises a winding unit, a drive unit, a fixing unit and a control unit, wherein the fixing unit comprises a fixed first mounting plate; the drive unit comprises a first motor fixed on the first mounting plate and a lift rack driven by the first motor, and the winding unit is fixed on the lift rack; the winding unit comprises a winding needle, a winding motor and a traversing module, the winding motor is used for driving the winding need to wind wires and drive the traversing module to drive the winding unit to traverse wires; and the control unit is used for controlling the drive unit to drive positioning of the winding unit and controlling the winding unit to wind wires. The invention also provides a winding machine comprising the winding device. By adopting the winding unit, the drive unit, the fixing unit and the control unit which work cooperatively, so that automatic operation of stator coil winding can be realized; and the drive unit drives positioning of the winding unit, so the positioning accuracy of winding can be improved, and the winding quality of the stator coil can be improved.

Description

technical field [0001] The invention relates to a winding device and a winding machine comprising the winding device. Background technique [0002] At present, the resolver has been widely used in hybrid electric vehicles and pure electric vehicles, and is one of the indispensable auto parts. The winding precision of the resolver stator coil directly affects the control strategy of the entire vehicle. Since the stator coils of the resolver are basically wound by hand in actual production, the efficiency is low and the winding quality of the stator coil cannot be guaranteed, which leads to a relatively high defect rate of the resolver. The stator coils of each resolver may be different. When applied to hybrid electric vehicles and pure electric vehicles, the control strategy may have to be adjusted appropriately according to the difference of the resolver, which is not conducive to the mass production of hybrid electric vehicles and pure electric vehicles. .
