Description

Technical Field

[0001] The utility model belongs to the technical field of motor tooling, in particular to a coil winding device. Background Art

[0002] A motor is a device that converts electrical energy into mechanical energy based on the principle of electromagnetic induction. It is mainly divided into electric motors and generators. The main function of the motor is to generate driving torque and serve as a power source for electrical appliances or various machines, while the main function of the generator is to convert mechanical energy into electrical energy. The motor is equipped with a coil inside. The number of turns of the coil can directly affect the strength of the magnetic field. It is one of the indispensable components in motor production. In order to adapt to the use requirements of different application scenarios, the stators of different power ranges are usually set with different lengths, which leads to different lengths of wires in the stator slots. Therefore, the coils need to be wound into different sizes.

[0003] After searching, it was found that the utility model patent with the publication (announcement) number CN215528830U discloses a motor coil winding device, including a winding frame, a bobbin and a winding rod. The side wall of the winding frame is rotatably connected to a rotating roller, and the bobbin is sleeved on the outer surface of the rotating roller. A limiting structure is provided between the bobbin and the winding frame. A driving plate is provided on one side of the winding frame. An adjustment structure is provided between the winding rod and the driving plate. The top of the side wall of the winding frame is fixedly connected to a motor. In this utility model, the spacing between the winding rods can be changed by manual control, so that the coil size can be flexibly adjusted to meet the winding requirements of wires of different lengths. The adaptability is wider, the adjustment is relatively simple and convenient, and the overall winding can be completed automatically without manual continuous operation, which greatly reduces labor intensity. The bobbin is provided with a limiting structure. When the wire is not fully used, the wire can be fixed by the limiting structure to prevent one end of the wire from losing tension and becoming loose and falling off, affecting subsequent operations.

[0004] However, in actual use, it was found that there was a lack of tension adjustment mechanism during the winding process of the wire, resulting in the coils formed by the wire wound on the surface of the winding rod 3 being of varying tightness and quality. In addition, when the driving plate 4 rotates, it has many surface parts and is prone to shaking. Therefore, it is necessary to design a coil winding device to solve the above problems.

Through the setting of the rollers 11, when the driving plate 2 is on the guide ring 1 When the inner cavity of 0 rotates, the roller 11 rolls in the groove of the guide ring 10, thereby reducing the friction resistance between the driving plate 2 and the guide ring 10, making the driving plate 2 rotate more smoothly. The inner cavity at the bottom of the sliding block 7 is equipped with a driving motor 13, and the output shaft of the driving motor 13 extends to the outside of the sliding block 7 and is fixedly connected to the gear 14.
