Description

Technical Field

[0001] The present invention relates to the technical field of winding machines, and more specifically, to a stable and efficient stator winding machine. Background Art

[0002] The stator includes a stator core and a stator winding. During production, the petal-shaped cores are successively enclosed to form an annular core. Insulators are assembled on both the upper and lower parts of the annular core to isolate the conductivity between the inner and outer circles of the core, thereby forming an annular stator core as a whole. Finally, a stator winding is formed by winding wires on the annular stator core. When winding, the wires are wound around the insulator with one petal of the core as the smallest unit, and the core is wrapped by the insulator. After the winding of one petal of the core is completed, the winding proceeds to the next adjacent petal of the core. Currently, the stator winding methods on the market are divided into manual winding and mechanical winding. Manual winding usually uses a simple device to wind the core, resulting in low production efficiency of stator winding, unstable winding quality, loose winding, and serious waste of winding wires. Most of the current mechanical winding methods on the market use a single wire to continuously wind the stator. After the stator is wound once, the wire is cut. When the copper wire is wound around different winding seats, the copper wire is usually first wound around the winding column and then wound around the winding seat. This winding method significantly increases the number of winding wire ends on the core, increases the waste of winding wires, and also affects the winding efficiency of the stator.

When the first wire winding base on the stator 26 is wound forward, the horizontal wire pulling part will pull the copper wire outwards to a predetermined position. At this time, the first vertical wire blocking part will descend to block the retraction of the copper wire. At this time, the rotating disk rotates, so that the second wire winding base on the stator 26 rotates to the winding position and then starts to wind reversely. After the reverse winding is completed, the horizontal wire pulling part will pull the copper wire outwards in the radial direction to a predetermined position, and then the second wire blocking part will descend to block the retraction of the copper wire. The second wire winding base and the first wire winding base are adjacent to each other. By adopting the method of winding forward and backward alternately for each adjacent wire winding base, the surplus of the wire winding head is effectively reduced, the copper wire is effectively saved, the production efficiency is improved, and at the same time, the production cost is reduced. The scissors include a first scissor and a second scissor. The first scissor is arranged on the tooling support plate. The second scissor is arranged on the upper support plate 2. The first scissor can directly cut the copper wire after winding on two adjacent wire winding bases. The second scissor is used when the vertical driving part is under maintenance and fails, and cannot push the radial contraction part and the reciprocating swing part to move vertically back and forth. The support cylinder will drive the stator 26 to move vertically back and forth through the tooling support plate, the rotating disk and the tooling plate, and finally realize the wire winding operation of the stator 26, effectively improving the reliability and continuity of the wire winding production operation of the stator 26.

[0046] The control part includes a PLC. The PLC is electrically connected to the vertical driving part, the radial contraction part, the reciprocating swing part, the tooling part and the coil adjustment part respectively. The PLC can control the activities of the corresponding motors and hydraulic cylinders in real time, which belongs to the prior art means and will not be elaborated here.

It can be fully applied to various fields suitable for the present invention. For those skilled in the art, additional modifications can be easily made. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to the specific details and the illustrated examples described herein.
