[0012] The beneficial effects of the utility model are:

[0013] 1. Through the wire management mechanism and reciprocating cylinder configured on the machine base, the bending problem of the stator coil lead wire is effectively solved.

Whether it is a single-direction bend or an intertwined lead-out wire, fine straightening can be achieved, which enhances the device's adaptability and handling capabilities for various stator coil lead-out wire arrangement problems.

[0015] 3. The structural design of the wire-management mechanism has been further improved. Through the multi-layer first combing plate and the second combing plate, and the first combing teeth with stepped length, the bottom walls of the tooth grooves of the multi-layer first combing plate form the first straightening surface, and the bottom walls of the tooth grooves of the multi-layer second combing plate form the second straightening surface.

This enables the device to have the ability to handle complex and crossed conditions of the lead-out wires. Whether it is a single-direction bend or an intertwined lead-out wire, it can achieve refined straightening, which enhances the device's adaptability and handling capabilities for various stator coil lead-out wire arrangement problems.

[0016] 4. The second combing teeth are arranged in a stepped manner, and the length of the first combing teeth of the multi-layer second combing plate gradually decreases in the first direction. With such a design, the first wire-management part and the second wire-management part can manage wires simultaneously, and can achieve fine straightening regardless of the bending in a single direction or the intertwined lead wires, thereby improving the wire-management efficiency.

[0017] 5. A linear telescopic mechanism and a third wire-management unit are introduced. The linear telescopic mechanism drives the stator coil to move back and forth along the central axis of the stator coil, so that the third wire-management unit pre-combs the stator coil lead-out wires from the lead-out starting end to the lead-out terminal end. This design can pre-solve some cross-entanglement problems, and then cooperate with the first wire-management unit and the second wire-management unit to carry out in-depth and detailed straightening. This improvement reflects the pre-positioning and efficiency of the handling of the lead-out wire crossing problem, forming a hierarchical combing mechanism, which greatly improves the integrity and accuracy of the straightening process.

[0018] 6. The addition of a rotating mechanism and a laser displacement sensor enables precise control of the position of the stator coil lead wire. The data detected by the laser displacement sensor is used to control the rotation of the rotating mechanism and accurately adjust the position of the stator coil to ensure that the lead wire is always at the intersection of the first and second wire management parts, so as to perform accurate and efficient straightening work. This design greatly improves the intelligence level and straightening accuracy of the device, which is conducive to ensuring the stability of the entire production process and the consistency of product quality.

[0035] Reference Figures 1 to 11 The utility model provides a wire management device for straightening the lead wires of stator coils.

[0036] In some embodiments, a wire-managing device for straightening stator coil lead wires includes a machine base 1 and a stator coil 2, wherein the machine base 1 is provided with a mounting structure for mounting the stator coil 2, and further includes a wire-managing mechanism and a reciprocating cylinder 3, wherein the wire-managing mechanism and the reciprocating cylinder 3 are mounted on the machine base 1, and the wire-managing mechanism includes a first wire-managing portion 4 and a second wire-managing portion 5, wherein the first wire-managing portion 4 and the second wire-managing portion 5 are relatively arranged on both sides of the central axis of the stator coil 2, wherein one end of the first wire-managing portion 4 away from the stator coil 2 is connected to the reciprocating cylinder 3, and the other end is provided with a plurality of first combing teeth 41, wherein tooth grooves are formed between adjacent first combing teeth 41, and the second wire-managing portion 5 away from the stator coil 2 One end is connected to the reciprocating cylinder 3, and the other end is provided with a plurality of second combing teeth 51, and tooth grooves are formed between adjacent second combing teeth 51. The bottom wall of the tooth groove of at least one of the first wire-winding part 4 and the second wire-winding part 5 corresponds to the extension starting end position of the lead-out wire 21 of the stator coil 2. The reciprocating cylinder 3 pushes the first wire-winding part 4 and the second wire-winding part 5 to approach the stator coil 2 along a central axis perpendicular to the stator coil 2. The bottom wall of the tooth groove of the first wire-winding part 4 cooperates with the bottom wall of the tooth groove of the second wire-winding part 5, or the bottom wall of the tooth groove of the first wire-winding part 4 cooperates with the second combing teeth 51, or the first combing teeth 41 cooperates with the bottom wall of the tooth groove of the second wire-winding part 5, which is used for straightening the lead-out wire 21 of the stator coil 2.

[0037] It should be noted that, for the setting of the first combing tooth 41 and the second combing tooth 51, it can be set that the bottom wall of the tooth groove of the first combing tooth 41 or the second combing tooth 51 corresponds to the extended starting end of the lead wire 21 of the stator coil 2, at this time, the bottom wall of the tooth groove of the first wire-laying part 4 cooperates with the bottom wall of the tooth groove of the second wire-laying part 5, or the first combing tooth 41 cooperates with the bottom wall of the tooth groove of the second wire-laying part 5, at this time, the tooth groove width of the bottom wall of the tooth groove of the first wire-laying part 4 or the second wire-laying part 5 is slightly larger than the diameter of the lead wire 21, so as to ensure that the tooth groove of the first wire-laying part 4 or the second wire-laying part 5 can be at least Partially wrapping the lead wire 21 of the stator coil 2 can ensure the straightening of the bends in all directions; it can also be set that the bottom wall of the tooth slot of the first wire-winding part 4 and the second wire-winding part 5 both correspond to the extended starting end of the lead wire 21 of the stator coil 2, and the bottom wall of the tooth slot of the first wire-winding part 4 cooperates with the bottom wall of the tooth slot of the second wire-winding part 5. At this time, the tooth slot width of the bottom wall of the tooth slot of the first wire-winding part 4 and the second wire-winding part 5 is slightly larger than the diameter of the lead wire 21, so as to ensure that the tooth slots of the first wire-winding part 4 and the second wire-winding part 5 can wrap the lead wire 21 of the stator coil 2 together, and can ensure the straightening of the bends in all directions. The tooth slot width of the bottom wall of the tooth slot refers to the width of the bottom wall of the tooth slot, that is, the distance between two adjacent teeth at the root of the tooth.

[0038] The thickness of the first wire-managing portion 4 and the second wire-managing portion 5 is adaptively adjusted according to the length of the lead-out wire 21 of the stator coil 2. A stepped first wire-managing portion 4 can also be provided, with the direction from the extended starting end of the lead-out wire 21 pointing to the end being the first direction, the first direction being parallel to the central axis of the stator coil 2, the length of the first combing tooth 41 gradually decreasing in the first direction, the direction from the tooth top to the tooth root of the first combing tooth 41 being the second direction, the tooth width of the first combing tooth 41 gradually increasing in the second direction, the tooth groove bottom wall of the first combing tooth 41 being parallel to the central axis of the stator coil 2, at this time, the second combing tooth 51 of the second wire-managing portion 5 is designed to be in shape matching the tooth groove of the first wire-managing portion 4, to ensure that the lead-out wire 21 of the stator coil 2 is pressed straight in the tooth groove bottom wall provided parallel to the central axis of the stator coil 2, the stepped first wire-managing portion 4 can ensure that the possible crossing problem of the lead-out wire 21 of the stator coil 2 is effectively solved. It can ensure that the lead wire 21 is fully straightened, thereby improving the arrangement order of the lead wire 21 of the stator coil 2 and being able to be accurately pressed into the slot later without causing wire skin damage or mismatch between the lead wire 21 and the slot, thereby improving the efficiency and product quality of the motor production process.

[0039] In some embodiments, the first combing teeth 41 of the first wire organizing portion 4 are arranged in a stepped manner, with the direction from the extended starting end of the lead wire 21 pointing to the end being the first direction, the first direction is parallel to the central axis of the stator coil 2, the length of the first combing teeth 41 gradually decreases in the first direction, the direction from the tooth top to the tooth root of the first combing tooth 41 is the second direction, the tooth width of the first combing tooth 41 gradually increases in the second direction, the bottom wall of the tooth groove of the first wire organizing portion 4 constitutes a first straightening surface, the first straightening surface is parallel to the central axis of the stator coil 2, the second combing teeth 51 of the second wire organizing portion 5 are arranged in a stepped manner, the length of the second combing teeth 51 gradually decreases in the first direction, and the straightening surface of the first wire organizing portion 4 cooperates with the second combing teeth 51.

[0040] This arrangement ensures that the first combing tooth 41 close to the stator coil 2 first enters the root gap of the lead wire 21 of the stator coil 2, and under the action of the reciprocating cylinder 3, continues to go deeper, and the stepped first combing tooth 41 is gradually inserted into the gap between the lead wires 21. Since the tooth width of the first combing tooth 41 gradually increases in the second direction, the crossed wires are pushed apart, and finally the lead wire 21 is located at the bottom wall of the tooth groove of the first wire organizing part 4. The second combing tooth 51 on the right side enters the tooth groove of the first wire organizing part 4, presses the lead wire 21, and completes the straightening of the lead wire 21.

[0041] In some embodiments, the first wire organizing portion 4 includes multiple layers of first combing plates 42, and there are first gaps 43 between the first combing plates 42 of adjacent layers. The first combing teeth 41 are arranged in steps, with the direction from the extended starting end of the lead wire 21 to the end being the first direction, and the first direction is parallel to the central axis of the stator coil 2. The length of the first combing teeth 41 gradually decreases in the first direction, and the direction from the tooth top to the tooth root of the first combing tooth 41 is the second direction. The tooth width of the first combing teeth 41 gradually increases in the second direction. The bottom walls of the tooth grooves of the multiple layers of the first combing plates 42 constitute a first straightening surface, and the first straightening surface is parallel to the central axis of the stator coil 2. The second wire organizing portion 5 is correspondingly provided with multiple layers of second combing plates 52, and there are second gaps 53 between the second combing plates 52 of adjacent layers. The bottom walls of the tooth grooves of the multiple layers of the second combing plates 52 constitute a second straightening surface, and the second straightening surface is parallel to the central axis of the stator coil 2. The first gap 43 is gap-matched with the second combing plate 52, the second gap 53 is gap-matched with the first combing plate 42, and the first straightening surface is matched with the second straightening surface.

[0042] Such a design further improves the structural design of the wire management mechanism. Through the multi-layer first combing plate 42 and the second combing plate 52, and the stepped first combing teeth 41 and the second combing teeth 51 with gradually varying lengths, the device has the ability to handle complex and crossed conditions of the lead wires 21. Whether it is a single-direction bend or an intertwined lead wire, fine straightening can be achieved, thereby enhancing the device's adaptability and handling capabilities for various stator coil 2 lead wire 21 arrangement problems.

[0043] It should be noted that the thickness setting of the multi-layer first combing plate 42 and the second combing plate 52 can be set to the same thickness or different thicknesses. It is only necessary to ensure that the first gap 43 and the second combing plate 52 can be gap-matched, and the second gap 53 and the first combing plate 42 can be gap-matched to ensure that the lead wire 21 of the stator coil 2 is straightened continuously without partial bending.

[0044] The first combing teeth 41 are arranged in a stepped manner, and the length of the first combing teeth 41 gradually decreases in the first direction. Such an arrangement ensures that the first combing teeth 41 at the starting end in the first direction are first inserted from the root of the lead wire 21 of the stator coil 2, and continue to go deeper under the action of the reciprocating cylinder 3, and are inserted into the gaps between the lead wires 21 layer by layer. Since the tooth width of the first combing teeth 41 gradually increases in the second direction, and then the cross wires are gradually pushed away, the tooth grooves of the first combing plate 42 and the tooth grooves of the second combing plate 52 form a quadrilateral area. Under the advancement of the reciprocating cylinder 3, the quadrilateral area is continuously reduced, and the first gap 43 is matched with the gap of the second combing plate 52, and when the second gap 53 is matched with the gap of the first combing plate 42, the first straightening surface and the second straightening surface clamp the lead wire 21 to complete the straightening of the lead wire 21. This design solves the problem of the lead wires 21 crossing each other, and can adapt to a variety of wire management environments, such as bending in a single direction, bending in multiple directions, and the situation where the lead wires 21 are intertwined.

[0045] In some embodiments, the second combing teeth 42 are arranged in steps, and the length of the second combing teeth 42 gradually decreases in the first direction, and the direction from the tooth top to the tooth root of the second combing teeth 42 is the third direction, and the tooth width of the second combing teeth 42 gradually increases in the third direction. In this way, the first wire-management part 4 and the second wire-management part 5 are synchronized to manage the wires, and the wire-management efficiency is improved on the original basis to cope with the bending and crossing conditions of the lead-out wires 21. The first combing teeth 41 and the second combing teeth 51 are both arranged in steps, and the lengths of the first combing teeth 41 and the second combing teeth 51 gradually decrease in the first direction. This arrangement ensures that the first combing teeth 41 and the second combing teeth 51 at the starting end in the first direction are first inserted from the root of the lead wire 21 of the stator coil 2, and continue to go deeper under the action of the reciprocating cylinder 3, and are inserted into the gaps between the lead wires 21 layer by layer. Since the tooth width of the first combing teeth 41 gradually increases in the second direction, the tooth width of the second combing teeth 51 gradually increases in the third direction, and then the cross lines are gradually opened, and the tooth grooves of the first combing plate 42 and the tooth grooves of the second combing plate 52 form a quadrilateral area. Under the advancement of the reciprocating cylinder 3, the quadrilateral area is continuously reduced, and the first straightening surface and the second straightening surface clamp the lead wire 21 to complete the straightening of the lead wire 21.

[0046] In some embodiments, it also includes a linear telescopic mechanism 7 and a third wire-managing portion 6. The linear telescopic mechanism 7 is installed on the machine base 1, and is used to control the reciprocating movement of the stator wire 2 along the central axis of the stator coil 2. The third wire-managing portion 6 and the first wire-managing portion 4 are located on the same side of the stator coil 2, or the third wire-managing portion 6 and the second wire-managing portion 5 are located on the same side of the stator coil 2. One end of the third wire-managing portion 6 is connected to the reciprocating cylinder 3, and the other end is provided with a plurality of third combing teeth 61. Tooth grooves are formed between adjacent third combing teeth 61. The tooth groove bottom wall of the third wire-managing portion 6 corresponds to the extension starting end position of the lead-out wire 21 of the stator coil 2. The reciprocating cylinder 3 pushes the third wire-managing portion 6 to approach the stator coil 2 along the central axis perpendicular to the stator coil 2.

[0047] In this embodiment, a linear telescopic mechanism 7 and a third wire-guiding portion 6 are introduced. The linear telescopic mechanism 7 drives the stator coil 2 to move back and forth along the central axis of the stator coil 2, so that the third wire-guiding portion 6 pre-combs the lead-out wires 21 of the stator coil 2 from the lead-out starting end to the lead-out terminal end. This design can pre-solve some cross-entanglement problems, and then cooperate with the first wire-guiding portion 4 and the second wire-guiding portion 5 to perform in-depth and detailed straightening. This improvement reflects the pre-positioning and efficiency of the processing of the crossing problem of the lead-out wires 21, forming a hierarchical combing mechanism, which greatly improves the integrity and accuracy of the straightening process.

[0048] In some embodiments, a rotating mechanism 8 is further included, which is used to drive the stator coil 2 to rotate around the central axis of the stator coil 2. A positioning groove is provided on the surface of the stator coil 2, and a laser displacement sensor 9 for detecting the displacement of the positioning groove is provided on the machine base 1. The laser displacement sensor 9 is electrically connected to the rotating mechanism 8. When the positioning groove is detected by the laser displacement sensor 9, the rotating mechanism 8 is controlled to stop rotating, which is used for positioning the stator coil 2.

[0049] In this embodiment, a rotating mechanism 8 and a laser displacement sensor 9 are added to achieve accurate control of the position of the lead wire 21 of the stator coil 2. The data detected by the laser displacement sensor 9 is used to control the rotation of the rotating mechanism 8, accurately adjust the position of the stator coil 2, and ensure that the lead wire 21 is always at the intersection position set by the first wire management part 4 and the second wire management part 5, so as to perform accurate and efficient straightening work. This design greatly improves the intelligence level and straightening accuracy of the device, which is conducive to ensuring the stability of the entire production process and the consistency of product quality. In order to more accurately control the position of the stator coil 2, a rotation compensation mechanism can be set. When the laser displacement sensor 9 detects the positioning groove on the stator coil 2, the rotating mechanism 8 stops rotating, so that the stator coil 2 stays at the specified position. At this time, there may be deviations caused by the reaction time of the control circuit, and the stator coil 2 can be corrected and rotated to a certain angle. It should be noted that the computer program involved in the data detected by the laser displacement sensor 9 to control the rotation of the rotating mechanism 8 is a known technology and has been commonly used in the market.
