Description

Technical Field

[0001] The invention relates to the field of winding equipment technology, in particular to a winding machine for a motor stator and a winding method thereof. Background Art

[0002] The stator of the motor is the stationary part of the motor. The stator is composed of three parts: the stator core (pole blocks, the stator is generally composed of 12 pole blocks), the stator winding and the machine base. The stator winding is usually wound on the stator core using a flying fork winding mechanism. The flying fork winding mechanism in the prior art generally includes a power source, an eccentric wheel, a guide rod, a slider and a flying fork rod. The power source drives the eccentric wheel to rotate, and the eccentric roller of the eccentric wheel abuts the slider, so that the slider moves up and down along the guide rod, and then the flying fork rod fixed to the slider also moves up and down, realizing the traction effect of the flying fork rod on the copper wire. Although the aforementioned flying fork winding mechanism has a certain degree of automated operation, it still requires a lot of manual assistance and is inefficient; and since manual operation is prone to errors, it is easy to produce defective products. Therefore, the existing winding machine should be improved to solve the above problems. Summary of the invention

The four wire drums 80 correspond to the four wire tensioners 70 one by one.

Initially, the end of the wire passes through the flying fork arm 521 and hangs on the wire pressing block 643 (hanging the wire). The flying fork arm 521 rotates to wind the wire around the pole block of the stator. As the wire is wound around the pole block, the upper wire block 531 and the lower wire block 532 move backward to make the wire evenly distributed from front to back on the pole block (the upper wire block 531 moves backward first, and then the lower wire block 532 moves backward again); as the number of turns of the wire wound on the pole block increases and the thickness increases, the upper wire block 531 and the lower wire block 532 will open to each other to adapt to the pole block with more turns of wire. After the winding is completed, the wire pressing block 643 will press down and cooperate with the cutter 642 to cut the wire. After the wire cutting is completed, the transfer mechanism 30 transfers the stator after wire cutting to the feeding mechanism 20, and at the same time, transfers the stator to be wound on the feeding mechanism 20 to the placement seat 44 of the material placement mechanism 40.

In addition, a large amount of manual labor is reduced, and production costs are reduced.
