Description

Technical Field

[0001] The present invention relates to the technical field of motor coil winding, and in particular to a motor coil winding device. Background Art

[0002] Motor coil winding is the process of winding the wire around the iron core of the motor stator or rotor according to a specific pattern to form an electromagnetic circuit. Its core function is to generate a rotating magnetic field in the air gap through current to achieve electromechanical energy conversion.

[0003] Motor stators can be divided into integrated stators and split stators according to their structures. The integrated stator is usually made of multiple silicon steel sheets stacked together, while the split stator is assembled from multiple stator blocks, such as the stator structure of the combined coil disclosed in patent CN1423392A.

[0004] Different stator coil forms require different winding methods. Most existing winding machines are designed for integrated stators, such as a motor stator winding machine disclosed in patent CN118889798A. When in use, the iron core is placed in the iron core placement tube, and then the pressure cover is placed on the top of the iron core. Multiple copper wires are passed around the first bearing and out of the wire outlet. The wire hook moves to the left to hook one end of the multiple copper wires, and the multiple copper wires are clamped between the wire hook and the wire outlet. After the multiple copper wires are hooked, the wire hook moves to the right, and the core shaft descends and extends into the iron core. The core shaft descends, rotates counterclockwise, rises, and rotates clockwise in sequence, thereby completing a circle of the copper wire around the iron core rib. Repeating the above actions can complete multiple circles of winding of the copper wire on one iron core rib.

[0005] It can be seen that the above winding machine is relatively complicated in structure and working process, and is not suitable for winding the split stator coil. Therefore, it is necessary to design a winding device for the split stator coil. Summary of the Invention

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of these features.

[0041] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in the present invention.

[0042] like Figure 1-2 As shown, the winding device of the motor coil in this embodiment includes a workbench 10, a support 20, a translation mechanism 30, a clamping mechanism 40, a winding mechanism 50, a wire clamping mechanism 60 and a wire cutting mechanism 70. The support 20 is fixedly arranged on the workbench 10, the translation mechanism 30 is arranged on the workbench 10 and is located on one side of the support 20, the clamping mechanism 40 is arranged above the translation mechanism 30, the winding mechanism 50 is rotatably arranged on the support 20, the wire clamping mechanism 60 is arranged on the front side of the winding mechanism 50, and the wire cutting mechanism 70 is arranged on one side of the wire clamping mechanism 60.

[0043] The translation mechanism 30 includes a linear module 31, a slide rail assembly 32 and a slide plate 33. The linear module 31 is fixedly set on the workbench 10, the slide rail assembly 32 is arranged parallel to both sides of the linear module 31, and the slide plate 33 is arranged above the linear module 31 and its two ends are slidably connected to the slide rail module 32.

[0044] The clamping mechanism 40 is disposed above the slide 33 . The linear module 31 drives the slide 33 to move, thereby driving the clamping mechanism 40 to move closer to or away from the winding mechanism 50 .

[0045] like Figure 3As shown, the clamping mechanism 40 includes a first connecting plate 41, a rotating motor 42, a locking cylinder 43 and a locking assembly 44. The first connecting plate 41 is fixedly set on the slide 33. The rotating motor 42 is set on one side of the first connecting plate 41 and is connected to the locking cylinder 43 through a pulley assembly 45. The locking assembly 44 is arranged above the locking cylinder 43 along the longitudinal transmission. The rotating motor 42 can drive the locking cylinder 43 and the locking assembly 44 to rotate intermittently through the pulley assembly 45 to adjust the position of the stator.

[0046] like Figure 4-5 As shown, the locking assembly 44 includes a locking sleeve 441, a lifting rod 442, an adjusting block 443 and a locking block 444. The locking sleeve 441 is longitudinally arranged above the locking cylinder 43, the lifting rod 442 is movably arranged inside the locking sleeve 441 and the bottom end is transmission-connected to the piston rod end of the locking cylinder 43, a wing plate 445 is provided on each side of the top of the locking sleeve 441, and a locking block 444 is slidingly provided on each side of each wing plate 445, the adjusting block 443 is arranged at the upper end of the lifting rod 442, and an inclined slot 446 is provided on the locking block 444, and the adjusting block 443 is slidingly arranged in the slot 446; a locking arm 447 is provided at the end of the locking block 444, and a stop arm 448 is provided at the side of the end of the wing plate 445 opposite to the locking arm 447, and a support block 449 is also provided on the lower side of the stop arm 448.

[0047] When the piston rod of the locking cylinder 43 moves downward, it can drive the lifting rod 442 to move downward, and then drive the adjusting block 443 to move vertically downward. Since the slot 446 that cooperates with it is set at an angle, the locking block 444 can be pushed to move horizontally toward the side of the wing plate 445 during the vertical downward movement of the adjusting block 443, and then the edge position of the stator is clamped through the cooperation of the locking arm 447 and the stop arm 448, and the bottom is supported by the support block 449.

[0048] When the piston rod of the locking cylinder 43 moves upward, it can drive the lifting rod 442 to move upward, and then drive the adjusting block 443 to move vertically upward, so that the locking block 444 moves horizontally to the side away from the wing plate 445, and then the locking arm 447 and the blocking arm 448 release the stator.

[0049] The stator is installed and disassembled in the above manner.

[0050] like Figure 2As shown, the winding mechanism 50 includes a winding motor 51, a threading shaft 52, a baffle 53 and a winding shaft 54. The winding motor 51 is arranged on the rear side of the support 20, the threading shaft 52 passes through the main shaft of the winding motor 51 and extends to the front side of the support 20, the baffle 53 is arranged on the front side of the threading shaft 52 through the second connecting plate 55, and a winding shaft 54 ​​is symmetrically provided on both sides of the threading shaft 52, and a threading hole 56 is provided inside the threading shaft 52 along its axial direction.

[0051] A fourth connecting frame 80 is further provided on the workbench 10 at the rear side of the support 20 , and a guide wheel 90 is provided on the top of the fourth connecting frame 80 , and the position of the guide wheel 90 corresponds to the position of the threading shaft 52 .

[0052] like Figure 6-7 As shown, a wire inlet groove 541 is provided on the side of the winding shaft 54 ​​and is penetrated radially. A wire outlet groove 542 is provided on the front side of the wire inlet groove 541 and is penetrated axially. The end of the wire outlet groove 542 is connected to the wire inlet groove 541. A winding wheel 543 is provided in the wire inlet groove 541 and is rotatably provided radially.

[0053] The wire is passed through the wire wheel 90 into the wire threading hole 56 of the threading shaft 52, passes through the wire threading hole 56, passes through the wire inlet groove 541, and then passes around the winding wheel 543, and then passes through the wire outlet groove 542 to the front side of the baffle 53, and finally is wound into one of the stator slots of the stator; when winding the wire for the first time or replacing the stator, the above steps are completed with manual assistance, and the winding process thereafter can be completed automatically by the device.

[0054] The winding motor 51 drives the threading shaft 52 and the winding shaft 54 ​​to rotate, and the wire can be wound into the stator slot through the winding shaft 54.

[0055] The wire clamping mechanism 60 includes a first lifting cylinder 61 and a clamping cylinder 62 . The first lifting cylinder 61 is set on the support 20 through a first connecting frame 63 , and the clamping cylinder 62 is fixedly connected to the piston rod end of the first lifting cylinder 61 through a second connecting frame 64 .

[0056] The first lifting cylinder 61 can drive the clamping cylinder 62 to move up and down through the second connecting frame 64, thereby adjusting the height of the clamping cylinder 62. The clamping cylinder 62 can drive the clamping claws at its end to move, thereby clamping the wire.

[0057] like Figure 8-9 As shown, the wire cutting mechanism 70 includes a second lifting cylinder 71, a shearing cylinder 72, a shearing support 73 and a cutter 74. The second lifting cylinder 71 is tiltedly arranged on the first connecting frame 63 through a third connecting frame 75 and is located between the clamping cylinder 62 and the baffle 53, so that the clamping cylinder 62 and the shearing support 73 are located on the same straight line, so as to facilitate the subsequent clamping and cutting of the wire.

[0058] The shearing cylinder 72 is transmission-set below the second lifting cylinder 71 , the shearing support 73 is fixedly set at the bottom of the shearing cylinder 72 , and the cutter 74 is slidingly set on one side of the shearing support 73 and transmission-connected to the piston rod of the shearing cylinder 72 .

[0059] Among them, a groove 76 for the wire to pass through is provided at the bottom of the shear support 73. The shear support 73 is a hollow structure. The piston rod of the shear cylinder 72 is movably arranged inside the shear support 73 and is fixedly connected to the cutter 74 on the side by a bolt 77.

[0060] During winding, the winding motor 51 drives the winding shaft 54 ​​to rotate, thereby winding the wire into one of the stator slots. Then the rotating motor 42 drives the locking assembly 44 to rotate one station, so that the adjacent stator slot is aligned with the winding station. Then the winding motor 51 continues to drive the winding shaft 54 ​​to rotate, winding the wire into the stator slot. This cycle is repeated to achieve the winding work of multiple stator slots.

[0061] After the winding is completed, the clamping cylinder 62 clamps the wire, and the shearing cylinder 72 drives the cutter 74 to move. The wire near the stator end is cut through the shearing action of the cutter 74 and the edge of the groove 76. The staff removes the wound stator and replaces it with a new stator, and pre-winds the wire in the stator slot. Then the winding device continues a new round of winding work.

[0062] The device can continuously wind two split stators or wind them separately. After the winding is completed, the two stators are assembled into a complete stator structure. The overall structure and working process of the present invention are relatively simple, which effectively improves the winding efficiency of the split stator.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. In addition, the technical solutions of the various embodiments may be combined with each other, but this must be based on the fact that they can be implemented by a person of ordinary skill in the art. If the combination of technical solutions is mutually inconsistent or cannot be implemented, it shall be deemed that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
