Description

Technical Field

[0001] This utility model specifically relates to the field of stator winding technology, and more specifically to a stepper motor stator winding device. Background Technology

[0002] Stator winding is a crucial step in motor manufacturing. The winding provides the rotor with a rotating magnetic field, and the quality of the winding directly affects the motor's efficiency. The stator has multiple winding pole blocks, and the winding pole blocks need to be wound sequentially. Before winding, the wire is hung in the first hanging position in the fixture to fix the movable wire. After the winding pole blocks are wound, the wire is hung in the second hanging position in the fixture. Then, the wire between the first hanging position and the winding pole block is cut. Finally, the wires on both sides of the second hanging position are cut. Existing winding machines have technical problems such as low winding efficiency, inconsistent winding tightness, and low wire cutting accuracy.

[0003] Currently, stator winding is done manually or through automated equipment. Manual winding is inefficient and cannot guarantee consistent winding tension, which may affect the motor's efficiency. While automated equipment can achieve efficient winding, traditional winding equipment adjusts the winding position. However, if the stator winding slots are narrow, the winding may come into contact with adjacent slots, preventing effective winding of any single slot.

[0004] A search revealed Chinese Patent Publication No. CN202310364317.2, which discloses a water pump motor stator coil installation device. The device includes a movable frame, a frame body mounted on top of the movable frame, a support column for fixing the stator mounted on the frame body, a flying fork winding mechanism on one side of the support column, a transmission mechanism mounted on the frame body, the transmission mechanism driving the flying fork winding mechanism to rotate, a frame mounted on the outer side of the stator, with winding grooves formed between adjacent frames, the rotation surface of the flying fork winding mechanism being perpendicular to the length direction of the frame, and the rotation of the flying fork winding mechanism winding enameled wire onto the frames outside the adjacent winding grooves. A protective plate is mounted on the frame body near the support column, and a partition is mounted on the protective plate.

[0005] In the aforementioned patent, the winding device winds the stator by moving the winding tube back and forth to wind the wire onto the stator. However, during the winding process, the end of the winding tube needs to be located inside the winding slot. This may cause interference between the winding tube and the winding slots on both sides of the stator, preventing the two winding tubes from effectively rotating and winding along the winding slots, thus reducing work efficiency and potentially affecting the motor's efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a stepper motor stator winding device. In this structure, the winding wire passes through two winding tubes, which are rotated by a rotating shaft. The positioning block is connected to the rotating shaft through a bearing, which effectively allows the winding wire to slide into the winding groove through the arc-shaped surfaces on both sides of the positioning block. Two symmetrical arc-shaped plates are also provided on both sides of the winding groove to ensure accurate winding position during winding. A second rotary motor enables the two lead screws to rotate synchronously through a second connecting belt, realizing the lateral movement of the slider, thereby effectively adjusting the distance between the stator and the winding wire on the placement platform, thus effectively ensuring the quality of winding and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A stepper motor stator winding device includes a worktable with a double round head slot on its top. A winding assembly is fixedly installed at one end of the worktable away from the end with the double round head slot. The winding assembly includes a housing. A rotating shaft is movably mounted on the side wall of the housing via bearings. A positioning block is mounted on the end of the rotating shaft away from the housing via bearings. The positioning block is U-shaped, and its two sides are arc-shaped.

[0009] A double-headed plate is fixedly installed on the rotating shaft between the housing and the positioning block; winding tubes are fixedly installed at both ends of the double-headed plate;

[0010] As a further technical solution of this utility model, a movable component is movably installed in the double round head groove opened on the workbench; the movable component includes a placement platform that is fixedly engaged with the motor stator; the placement platform passes through the double round head groove opened on the workbench and is fixedly installed with a third rotary motor; the third rotary motor is fixedly installed on the slider.

[0011] As a further technical solution of this utility model, the two ends of the slider are integrally provided with symmetrical ear plates; the ear plates are threadedly connected to the lead screw; the two ends of the lead screw are installed at the bottom of the top plate of the worktable through bearings with seats.

[0012] As a further technical solution of this utility model, the two lead screws are connected to the output shaft of the second rotary motor through a second connecting belt at the same end, and the second connecting belt is arranged in a triangle.

[0013] As a further technical solution of this utility model, the second rotary motor is fixedly installed at the bottom of the top plate of the workbench by a Z-shaped frame;

[0014] As a further technical solution of this utility model, a mating assembly is fixedly installed on the workbench. The mating assembly includes two symmetrical protective grilles and two symmetrical support rods. An arc-shaped plate is fixedly installed on the top of each support rod. The ends of the two arc-shaped plates are located on both sides of the positioning block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the motor stator is fixedly mounted on a placement platform during use, and the bottom of the placement platform is fixedly mounted to the output shaft of the third rotary motor. This enables the motor stator to rotate automatically during winding, thereby effectively enabling winding processing on different winding slots.

[0017] In this invention, during winding, the winding wire passes through the winding tubes installed at both ends of the double-ended plate. The first rotating motor drives the first connecting belt to rotate, thereby rotating the shaft. The winding tubes rotate synchronously with the shaft, allowing the winding wire to slide into the winding groove through the arc surfaces on both sides of the positioning block, ensuring the quality of the winding wire. At the same time, arc-shaped plates are provided on both sides of the opening end of the winding groove, which effectively prevents the winding wire from contacting the winding groove on both sides of the winding groove.

[0018] In this invention, during the winding process, to ensure that the winding fills the winding slot, a second rotary motor drives a second connecting belt to achieve synchronous and unidirectional rotation of two lead screws. The lead screws engage with the ear plates at both ends of the slider via threaded connections, enabling the slider to move back and forth. This effectively achieves the correct position between the winding and the winding slot, thereby effectively meeting the winding requirements and ensuring the working efficiency of the stator.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-8 In this embodiment of the present invention, a stepper motor stator winding device includes a workbench 1, the top of which has a double round head groove; a winding assembly 2 is fixedly installed at one end of the top of the workbench 1 away from the end with the double round head groove; the winding assembly 2 includes a housing 20; a rotating shaft 21 is movably installed on the side wall of the housing 20 via bearings; a positioning block 24 is installed at the end of the rotating shaft 21 away from the housing 20 via bearings; the positioning block 24 is U-shaped and its two sides are arc-shaped.

[0030] A double-headed plate 22 is fixedly installed on the rotating shaft 21 between the housing 20 and the positioning block 24; winding tubes 23 are fixedly installed at both ends of the double-headed plate 22.

[0031] A movable component 4 is movably installed in the double round head groove on the worktable 1; the movable component 4 includes a placement platform 40 that is fixedly engaged with the motor stator 5; the placement platform 40 passes through the double round head groove on the worktable 1 and is fixedly installed with the third rotary motor 48; the third rotary motor 48 is fixedly installed on the slider 41.

[0032] By adopting the above technical solution, when in use, the motor stator 5 is fixedly installed on the placement platform 40, and the bottom of the placement platform 40 is fixedly installed with the output shaft of the third rotary motor 48. This enables the motor stator 5 to rotate automatically when winding, thereby effectively realizing the winding process for different winding slots.

[0033] The slider 41 has symmetrical ear plates 42 integrally formed at both ends; the ear plates 42 are threadedly connected to the lead screw 43; the two ends of the lead screw 43 are installed at the bottom of the top plate of the worktable 1 through bearings 44 with seats.

[0034] In this embodiment, the two lead screws 43 are connected to the output shaft of the second rotary motor 46 at the same end through a second connecting belt 45, which is arranged in a triangular shape.

[0035] By adopting the above technical solution, during winding, the winding wire passes through the winding tubes 23 installed at both ends of the double-ended plate 22, and the first connecting belt 26 is driven to rotate by the first rotary motor 25, thereby realizing the rotation of the rotating shaft 21. The winding tubes 23 rotate synchronously with the rotating shaft 21, so that the winding wire slides into the winding groove through the arc surfaces on both sides of the positioning block 24, ensuring the quality of the winding wire. At the same time, arc plates 31 are provided on both sides of the opening end of the winding groove, which effectively avoids the winding wire from contacting the winding groove on both sides of the winding groove.

[0036] In this embodiment, the second rotary motor 46 is fixedly installed at the bottom of the top plate of the workbench 1 by means of a Z-shaped frame 47;

[0037] The workbench 1 is fixedly installed with a mating assembly 3, which includes two symmetrical protective grilles 30 and two symmetrical support rods 32; each support rod 32 has an arc-shaped plate 31 fixedly installed on its top; the ends of the two arc-shaped plates 31 are located on both sides of the positioning block 24.

[0038] By adopting the above technical solution, in order to ensure that the winding fills the winding slot during the winding process, the second rotating motor 46 drives the second connecting belt 45 to realize the synchronous and co-rotation of the two lead screws 43.

[0039] The working principle of this utility model is as follows: When in use, the motor stator 5 is fixedly installed on the placement platform 40, and the bottom of the placement platform 40 is fixedly installed with the output shaft of the third rotary motor 48. This enables the motor stator 5 to rotate automatically when winding, thereby effectively realizing the winding process of different winding slots.

[0040] During winding, the winding wire passes through the winding tubes 23 installed at both ends of the double-ended plate 22. The first connecting belt 26 is driven to rotate by the first rotary motor 25, which in turn rotates the shaft 21. The winding tubes 23 rotate synchronously with the shaft 21, allowing the winding wire to slide into the winding groove through the arc surfaces on both sides of the positioning block 24, ensuring the quality of the winding wire. At the same time, arc plates 31 are provided on both sides of the opening end of the winding groove, which effectively prevents the winding wire from contacting the winding groove on both sides of the winding groove.

[0041] During the winding process, in order to ensure that the winding fills the winding slot, the second rotating motor 46 drives the second connecting belt 45 to realize the synchronous and co-rotation of the two lead screws 43. The lead screws 43 are threadedly engaged with the ear plates 42 at both ends of the slider 41 to realize the forward and backward movement of the slider 41, thereby effectively realizing the position between the winding and the winding slot, thus effectively meeting the winding requirements and ensuring the working efficiency of the stator.
