Abstract

The present invention provides a positioning mechanism for automatic feeding of a coil winding machine, which relates to the technical field of coil winding machines and includes: a workbench, on the left side of which there is a moving frame; on the upper right side of the workbench there is a mounting column; on the mounting column there is a driving seat; on the mounting column there is a rotating frame. Since the automatic winding and positioning effect of the coil is poor, there will be a deviation situation, resulting in the copper wire arrangement not being tight and neat enough. Moreover, when rotating and winding, due to the inertial effect, the copper wire is likely to become scattered, reducing the quality of the coil winding. In addition, during the rotating and winding process, the feeding of the copper wire is not stable enough, and it is extremely easy to become scattered and knotted, reducing the efficiency of automatic feeding, and solving the problems that in the existing motor stator coil winding machine during use, when rotating and winding, due to the inertial effect, the copper wire is likely to become scattered, reducing the quality of the coil winding. In addition, during the rotating and winding process, the feeding of the copper wire is not stable enough, and it is extremely easy to become scattered and knotted, reducing the efficiency of automatic feeding.

Description

Technical Field

[0001] The present invention relates to the technical field of coil winding machines, and in particular to a positioning mechanism for automatic feeding of a coil winding machine. Background Art

[0002] The motor stator is an important part of the starting motor of new energy vehicles. The stator consists of three parts: a stator core, a stator winding, and a frame. The stator winding refers to the winding installed on the stator, that is, the copper wire wound on the stator. The winding is a general term for a phase or the entire electromagnetic circuit composed of multiple coils or coil groups, and the coil is usually completed by an automatic winding machine.

[0003] When the existing motor stator coil winding machine is in use, due to the poor positioning effect of the automatic winding of the coil, the situation of deviation will occur, resulting in the copper wire arrangement not being tight and neat enough. Moreover, when rotating and winding, due to the inertial effect, the copper wire is likely to be scattered, reducing the winding quality of the coil. In addition, during the process of rotating and winding, the feeding of the copper wire is not stable enough, and it is extremely easy to be scattered and knotted, reducing the efficiency of automatic feeding.

[0015] The present invention provides a positioning mechanism for automatic feeding of a coil winding machine, which has the following beneficial effects:

[0016] In the present invention, the air cylinder provides power to push the moving frame to adjust rightward along the guide groove. The moving frame drives the motor stator to squeeze against the positioning seat. The copper wire is limited by the winding baffle and the positioning seat. At the same time, the servo motor drives the rotating shaft rod and the gear to rotate. By the meshing transmission of the gear and the toothed ring, the rotating frame can rotate around the mounting column as the axis, and the copper wire is guided by the wire guiding frame to wind reciprocally, thus realizing the automatic winding process of the coil of the motor stator. Among them, the winding baffle and the positioning seat cooperate with each other, and can effectively position during the copper wire winding, ensuring that the arrangement is more compact and neat.

[0017] In addition, during the process of winding the coil of the motor stator, the air cylinder drives the moving frame to gradually adjust leftward, so that the copper wire is wound orderly in the wire holes of the motor stator. At the same time, the elastic return of the compression spring is used to push the positioning seat to slide back to its original position. The limiting round rod drives the limiting slider to slide leftward along the limiting chute, so that the rubber pad and the rubber ring can be closely attached, thereby being able to quickly position the rotating frame, avoiding the rotating frame from continuing to rotate due to inertia, effectively preventing the copper wire from getting scattered, and improving the coil winding quality.

[0018] In addition, the present invention is provided with a rotating circular plate. Since the rotating circular plate rotates simultaneously with the rotating frame, the copper wire is guided by the guiding roller. By ensuring a parallel state, the copper wire feeding process is made more stable, and the elastic pressing plate is used to clamp and position the copper wire on the mounting material roller, avoiding winding and knotting during transportation, and effectively improving the automatic feeding efficiency.

On the basis of Embodiment 1, as Figures 7 to 9 shown, the rotating circular plate 7 is rotatably connected to the mounting column 3 through a bearing, and there are two connecting rods 701 provided on the left side of the rotating circular plate 7. The two connecting rods 701 are distributed symmetrically, and the left end of the connecting rod 701 is connected to the mounting column 3. A guiding through hole 702 is formed in the rotating circular plate 7, and two guiding rollers 703 are rotatably installed in the guiding through hole 702. The two guiding rollers 703 are distributed symmetrically. The copper wire 10 passes through the guiding through hole 702, and the guiding rollers 703 are in transmission connection with the copper wire 10;

[0053] A spline sleeve 801 is provided at the central position of the mounting material roller 8, and the spline sleeve 801 is slidably sleeved on the spline shaft 305 of the mounting column 3.
