[0002] The structure of the coreless motor rotor is as follows Figure 11 As shown, the commutator 20 includes a winding 22 and a commutator 20. The winding is a cup-shaped cylindrical coil made of self-adhesive polyurethane enameled wire wound on a special mold. The inner and outer surfaces of the cup-shaped cylindrical coil are coated with a retaining insulating adhesive and then cured at high temperature. The commutator is connected to the cup-shaped cylindrical coil, and the connection is coated with a retaining protective adhesive, also cured at high temperature. A set of circumferentially arranged winding leads 19 extend from the winding 22 and are welded to the pole pieces 23 of the commutator 20.

[0032] Reference Figure 1-11As shown, the present invention provides an automatic wire-managing device for a motor rotor, comprising: a mounting plate 1, a wire-positioning telescopic rod 2, a wire-pressing telescopic rod 3, a wire-positioning telescopic rod cylinder 4, and a wire-pressing telescopic rod cylinder 5. The mounting plate 1 is horizontally mounted on a frame 6. The wire-positioning telescopic rod 2 is circumferentially mounted on a wire-positioning telescopic rod slider 7 of the mounting plate 1. The wire-positioning telescopic rod slider 7 is slidably mounted on the mounting plate 1 via a slide rail seat 24. A wire-positioning head 8 is provided at the front end of the wire-positioning telescopic rod 2. When the wire-positioning telescopic rod 2 is extended into position, a positioning hole 21 is formed in the center of the wire-positioning head 8, which is compatible with the commutator 20 on the motor rotor, thereby positioning the motor rotor. Positioning slots 9 are formed between adjacent wire-positioning heads 8, which are compatible with the winding leads 19 on the motor rotor, thereby positioning and guiding the winding leads 19 of the motor rotor. The wire-pressing telescopic rod 3 is circularly mounted on the wire-pressing telescopic rod slider 11 of the mounting plate 1. The wire-pressing telescopic rod slider 11 is slidably mounted on the mounting plate 1 via a slide rail seat 24, and the wire-pressing telescopic rod 3 is positioned above and between adjacent wire-straightening and positioning telescopic rods 2. A wire-pressing head 12 is provided at the front end of the wire-pressing telescopic rod 3, and a wire-pressing plate 10 is located in the center of the lower end surface of each wire-pressing head 12, which is adapted to the positioning groove 9. The wire-straightening and positioning telescopic rod cylinder 4 drives the wire-straightening and positioning telescopic rod slider 7 to slide back and forth, thereby driving the wire-straightening and positioning telescopic rod 2 to extend and retract. The wire-pressing telescopic rod cylinder 5 drives the wire-pressing telescopic rod slider 11 to slide back and forth, thereby driving the wire-pressing telescopic rod 3 to extend and retract. The number of wire-straightening and positioning telescopic rods 2 and 3 is determined by the number of phases of the motor rotor. Typically, a coreless motor rotor has five phases, so there are five wire-pressing telescopic rods 3 and 3. During operation, the wire-straightening and positioning telescopic rod 2 is first extended to its proper position, and then the wire-pressing telescopic rod 3 is extended; after finishing, the two rods are retracted synchronously.

[0033] Preferably, the mounting plate 1 is mounted on a linear slide rail 13 of the frame 6, and the mounting plate 1 can slide up and down through the linear slide rail 13, thereby controlling the contact or separation of the wire-straightening positioning telescopic rod 2, the wire-pressing telescopic rod 3 and the motor rotor.

[0034] Preferably, the wire-straightening and positioning telescopic rods 2 and wire-pressing telescopic rods 3 are mounted in a circular pattern on the bottom of the mounting plate 1, while the wire-straightening and positioning telescopic rod cylinders 4 and wire-pressing telescopic rod cylinders 5 are mounted in a circular pattern on the top of the mounting plate 1. Each of the wire-straightening and positioning telescopic rod cylinders 4 and wire-pressing telescopic rod cylinders 5 drives the sliding of the wire-straightening and positioning telescopic rod sliders 7 and wire-pressing telescopic rod sliders 11, respectively, via a linkage plate 14. The linkage plate 14 is L-shaped, achieving a rational spatial layout while facilitating the bottom feeding mechanism to deliver the motor rotor to the wire-straightening and positioning telescopic rods 2 and wire-pressing telescopic rods 3 for sorting.

[0035] Preferably, an observation hole 15 is provided in the center of the mounting plate 1. When the wire-straightening positioning telescopic rod 2 and the wire-pressing telescopic rod 3 are extended into place, the wire-straightening positioning head 8 and the wire-pressing head 12 are located below the observation hole 15 to facilitate staff to observe the working condition of the equipment.

[0036] Preferably, the wire-straightening and positioning telescopic rods 2 and the wire-pressing telescopic rods 3 are installed in a circumferential and equally spaced manner. Since the winding leads 19 of the motor rotor are circumferentially and equally spaced, by installing the wire-straightening and positioning telescopic rods 2 and the wire-pressing telescopic rods 3 in a circumferential and equally spaced manner, the winding leads 19 can be straightened and pressed more accurately.

[0037] Preferably, the front end of the wire pressing plate 10 is provided with a first chamfer 16, which is preferably rounded. The ends of the wire spooling and positioning head 8 and the wire pressing head 12 are provided with a second chamfer 17, which is preferably chamfered. The chamfers protect the winding wires and prevent scratches caused by overly sharp tops.

[0038] Preferably, the winding positioning heads 8 are all triangular in shape. The triangular structure makes it easier to straighten the winding wires, and the inclined surfaces on both sides also serve as guides, allowing the winding leads 19 on the motor rotor to smoothly enter the positioning grooves 9.

[0039] Preferably, a guide opening 25 is provided between the rear ends of adjacent wire-straightening and positioning heads 8 , and the wire pressing plate 10 can be inserted into the positioning groove 9 more smoothly through the guide opening 25 .

[0040] Preferably, the frame 6 is provided with limit switches 18 at both ends corresponding to the mounting plate 1 to control the sliding stroke of the mounting plate 1 .

[0041] Working principle: When the feeding mechanism sends the motor rotor to the working position of this device, the linear slide rail is first used to slide the mounting plate down so that the wire-straightening positioning telescopic rod is aligned with the winding lead position of the motor rotor. The wire-straightening positioning telescopic rod cylinder is then used to push the wire-straightening positioning telescopic rod out. During the extension process of the wire-straightening positioning telescopic rod, the triangular wire-straightening positioning head is used to install the winding lead into the positioning groove for positioning. Finally, the wire-pressing telescopic rod is extended, and the wire-pressing plate is used to press the winding lead to the pole piece surface of the motor rotor and fit it to the pole piece surface. After completion, the next automatic welding process can be entered.

[0042] The above does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to the above-disclosed structures and technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
