[0022] The following are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.

[0023] like Figures 1 to 6 As shown, in order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a rotor automatic wire-managing device, which includes a control electrical box 4, a machine base 1, a rotor positioning seat 2 installed on the machine base 1, and an ejection mechanism 3 arranged below the rotor positioning seat 2, a rotor positioning groove 20 for positioning the commutator 02 of the rotor 01 is arranged in the middle of the rotor positioning seat 2, and the rotor positioning seat 2 is axially provided with a plurality of needle holes 21 along the central axis of the rotor positioning groove 20, and each needle hole 21 is respectively equipped with a wire-managing needle 22 arranged through it, and the head of each wire-managing needle 22 extends at least into the rotor positioning groove 20, and the tail of each wire-managing needle 22 is respectively driven and connected to the ejection mechanism 3, and the ejection mechanism 3 is electrically connected to the control electrical box 4. In actual application, the rotor 01 is installed on the rotor positioning seat 2, and the rotor positioning seat 2 positions the rotor 01 through the rotor positioning groove 20 to accurately confirm the installation angle of the rotor 01, so that the copper hook 03 of the commutator 02 and the wire-managing needle 22 are staggered and arranged, such as Figure 1-Figure 3 As shown, after the rotor automatic wire-managing device is started, the ejection mechanism 3 drives each wire-managing needle 22 to be ejected along the corresponding needle hole 21 respectively. At this time, the head of the wire-managing needle 22 is located between the two adjacent enameled wires 04 on the neck copper hook 03 to achieve the function of combing and dividing the wires. Compared with the prior art which adopts the manual dividing method, the present invention can complete the multi-slot combing work at one time, thereby greatly improving the production efficiency.

[0024] In a preferred embodiment, the inner wall of the end of each of the needle holes 21 is respectively provided with an elastic reset member 23, and the tail of each wire management needle 22 is respectively passed through the corresponding elastic reset member 23 and protrudes out of the corresponding needle hole 21. When the ejection mechanism 3 is retracted, the wire management needle 22 is automatically reset under the action of the elastic reset member 23, wherein the elastic reset member 23 is preferably a reset spring, which has a simple structure and low production cost.

[0025] like Figure 6 As shown, in a more specific implementation scheme, each of the wire organizing needles 22 is arranged at an inclination relative to the horizontal plane of the machine base 1, and the wire organizing needle 22 includes a needle body 220, a wire dividing hook 221 formed by extending from the head of the needle body 220, and a clamping platform 222 formed by extending from the tail of the needle body 220, and the elastic reset member 23 is sleeved on the needle body 220, and the end of the elastic reset member 23 is fixed to the clamping platform 222.

The two guide columns 33 are respectively installed on the opposite left and right sides of the lifting push plate 31. The lower part of the guide sleeve 32 abuts against the two guide columns 33 respectively. The inner wall of the upper part of the guide sleeve 32 is provided with a lifting guide surface. The guide sleeve 32 is sleeved on the outer side of the rotor positioning seat 2, wherein the lifting guide surface is an annular curved surface inclined relative to the horizontal plane, so that the tail of each wire management needle 22 can abut against the lifting guide surface.

[0029] In a further technical solution, a rotor chip positioning block 24 is provided on the upper part of the rotor positioning seat 2. The rotor chip positioning block 24 is provided with a plurality of magnetic mounting holes. A magnetic bead 25 is embedded in each magnetic mounting hole for magnetically cooperating with the iron core of the rotor 01 to fix the rotor 01. The structural design is ingenious, and there is no need to use additional fixing components to fix the rotor 01. The transverse cross-section of the rotor chip positioning block 24 is "C"-shaped, "U"-shaped, "O"-shaped or "U"-shaped.
