Description

Technical Field

[0001] The utility model relates to the technical field of motor winding, and more specifically, to a multi-strand motor winding auxiliary device. Background Art

[0002] The stranded wire used in motor winding refers to a wire composed of multiple tiny metal wires or thin copper wires. These tiny metal wires or thin copper wires are twisted together to form a thicker wire, i.e., stranded wire. The use of stranded wire can increase the flexibility and conductivity of the wire, while also reducing the resistance of the wire and improving the efficiency of the motor.

[0003] The motor winding process is to introduce multiple strands of wire into the winding machine, ensure that the ends of the multiple strands of wire are correctly fixed on the lead shaft on the winding machine, and then introduce the multiple strands of wire into the winding slot of the stator or rotor that needs to be wound to carry out the motor winding operation.

[0004] Traditional winding machines need to wrap multiple strands of wire along the winding groove. When the multiple strands of wire are combed, the multiple strands of wire need to be input straight and stretched tightly for transportation. Based on this, wrapping the multiple strands of wire around the winding groove can easily cause damage to the multiple strands of wire and the winding groove. In addition, as the multiple strands of wire are wrapped around the same winding groove multiple times, the required wrapping radius of the multiple strands of wire is gradually increasing. The wrapping process can easily cause the multiple strands of wire to be severely stretched, resulting in uneven thickness of the multiple strands of wire. Utility Model Content

[0023] A multi-strand motor winding auxiliary device, see Figure 1 and Figure 2, comprising a bracket 1, on which a first support roller 11, a linear module 13 and a second support roller 12 are arranged, on which a third support roller 14 is installed, and the linear module 13 drives the third support roller 14 to move linearly, and the connecting direction of the first support roller 11 and the second support roller 12 intersects with the moving direction of the third support roller 14;

[0024] The multi-strand wire 15 is supported by the first support roller 11 and passes through the third support roller 14 and the second support roller 12 successively. The first support roller 11, the second support roller 12 and the third support roller 14 form a triangular support for the multi-strand wire 15. The third support roller 14 is moved by the linear module 13 to change the circumference of the triangular support for the multi-strand wire 15, thereby changing the tightness of the multi-strand wire 15.

[0025] The present embodiment is based on the traditional motor winding process. When winding the winding groove, the multi-strand wire 15 needs to be wound along the winding groove. At the same time, when the multi-strand wire 15 is combed, the multi-strand wire 15 needs to be input straightly. The multi-strand wire 15 is transported in a taut and straight state. However, when winding the multi-strand wire 15 around the winding groove, the multi-strand wire 15 needs to be further pulled. As the multi-strand wire 15 is wound around the same winding groove multiple times, the required winding radius of the multi-strand wire 15 is gradually increasing. In this case, brute force pulling of the multi-strand wire 15 will not only damage the multi-strand wire 15, but also the winding groove around which the multi-strand wire 15 is wound is too tight, resulting in the multi-strand wire 15 wrapped around the winding groove being squeezed and deformed. In severe cases, the winding groove may be tilted outward or even damaged.

[0026] In this embodiment, the multi-strand wire 15 is supported by the first support roller 11 and passes through the third support roller 14 and the second support roller 12 in sequence. The multi-strand wire 15 enters from the first support roller 11, surrounds the third support roller 14, and is pulled out by the second support roller 12. The first support roller 11, the second support roller 12 and the third support roller 14 form a triangular support to provide stable support for the multi-strand wire 15. Based on the support frame of the bracket 1, the third support roller 14 is moved by the linear module 13 to change the triangular shape of the triangular support to change the tightness of the multi-strand wire 15. By alternating the tightening and relaxing states of the multi-strand wire 15, it is not only effective to facilitate the winding of the multi-strand wire 15, but also effectively avoid damage between the multi-strand wire 15 and the winding groove.

[0027] The moving direction of the linear module 13 in this embodiment is the moving direction of Z1 - Z2 in the drawing, which is perpendicular to the connecting direction of the first supporting roller 11 and the second supporting roller 12 .

[0028] Specifically, a driving roller 2 is provided on the bracket 1 , and the multi-strand wire 15 is wrapped around the driving roller 2 . The driving roller 2 is connected and driven to rotate by a driving member 21 to transport the multi-strand wire 15 . The driving member 21 is installed on the bracket 1 .

[0029] In order to realize the automatic conveying of the multi-strand wire 15, the driving member 21 is connected to drive the rotating driving roller 2 to drive the multi-strand wire 15 to be conveyed. In this embodiment, the driving member 21 is a motor.

[0030] Specifically, the bracket 1 is provided with a fourth support roller 17 and a fifth support roller 18, and an elastic support mechanism is provided between the fourth support roller 17 and the fifth support roller 18. The multi-strand wire 15 is supported at both ends of the line segment by the fourth support roller 17 and the fifth support roller 18, and the middle section of the multi-strand wire 15 is elastically supported by the elastic support mechanism to leave a spare line 16 of a preset length.

[0031] Since the multi-strand wire 15 is alternately in a state of tension and relaxation, the pulling and relaxation of any point in the multi-strand wire 15 will simultaneously cause traction and diffusion on both sides of any point in the multi-strand wire 15. Based on this, the fourth support roller 17 and the fifth support roller 18 support both ends of the line segment of the multi-strand wire 15, and the elastic support mechanism elastically supports the multi-strand wire 15 in the middle section of the multi-strand wire 15 to reserve a spare wire 16 of a preset length. The spare wire 16 is used to reserve sufficient linear length for the multi-strand wire 15 when tensioning and relaxing, which can effectively avoid damage to the multi-strand wire 15 caused by forcibly pulling the multi-strand wire 15.

[0032] The elastic support mechanism includes a first sliding block 3 sliding on the bracket 1, a sixth support roller 31 mounted on the first sliding block 3, and a first elastic member 32 connecting the first sliding block 3 and the bracket 1;

[0033] The multiple strands of wire 15 are wound around the sixth supporting roller 31 , and push the first elastic member 32 to perform elastic extrusion by squeezing the first sliding block 3 .

[0034] Furthermore, the elastic support mechanism also includes a second sliding block 33 sliding on the bracket 1, a seventh support roller 34 installed on the second sliding block 33, and a second elastic member 35 connecting the second sliding block 33 and the bracket 1, and the second sliding block 33 and the first sliding block 3 are arranged in opposition to each other, and the multiple strands of wire 15 are staggeredly clamped on the same horizontal plane of the surface of the bracket 1.

[0035] The second sliding block 33 and the first sliding block 3 are used to form a staggered clamping of the multi-strand wire 15 , and the length of the standby wire 16 is further extended under the elastic support of the first elastic member 32 and the second elastic member 35 .

[0036] The bracket 1 is provided with rails 36 for the first sliding block 3 and the second sliding block 33 to move. The rails 36 limit the moving directions of the first sliding block 3 and the second sliding block 33.

[0037] Specifically, the bracket 1 is provided with a support plate 4 for supporting the metal wire or the multi-strand wire 15, and the bracket 1 is provided with felt plates 41 distributed on both sides of the support plate 4, and the felt plates 41 and the support plate 4 form a clamping limit for the metal wire or the multi-strand wire 15. When the metal wire or the multi-strand wire 15 passes through the felt plates 41, the dust and impurities can be cleaned by using the felt plates 41.

[0038] The needle of this embodiment uses the method of clearing the metal wire, and the metal wire is transitionally pulled between the felt plate 41 and the fourth supporting roller 17 through the transition roller 19. The metal wire completes the multi-strand wire 15 of multiple metal wires twisted on the transition roller 19, and the limiting groove on the transition roller 19 promotes the twisting of multiple metal wires.

[0039] Furthermore, the position limiting clamping can provide reverse resistance when the backup line 16 is pulled, so that the backup line 11 can be straightened.

[0040] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
