Description

Technical Field

[0001] This utility model relates to the technical field of winding machines, and in particular to a motor rotor winding mechanism. Background Technology

[0002] With the continuous development of motor manufacturing technology, the requirements for motor performance and production efficiency are gradually increasing. The rotor winding process is a crucial step in motor production, placing high demands on winding precision and efficiency. Traditional rotor winding methods mainly rely on manual operation or simple semi-automatic equipment, which is not only inefficient but also makes it difficult to guarantee winding precision and consistency, easily leading to problems such as uneven winding, misaligned wires, and overlapping wires, affecting motor performance and service life.

[0003] A search revealed a Chinese patent document that discloses a dual-station winding device for a flying fork winding machine [Application No.: 202321037570.9, Publication No.: CN219513935U]. This device includes a frame on which a dual-station robotic arm, a dual-station winding main unit, a dual-station tooling storage platform, a dual-station iron core clamp storage platform, a dual-station wire clamping and cutting mechanism, and a dual-station winding table are mounted. Although this device can meet the winding requirements and has two stations, its structure is bulky, its efficiency can be further improved, and it cannot meet current production needs. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a motor rotor winding mechanism.

[0005] A motor rotor winding mechanism includes a winding device, a rotor indexing device, a wire pulling device, and a device housing, characterized in that: the winding device is mounted on the device housing, the rotor indexing device is mounted on the device housing, the wire pulling device is mounted on the device housing, the wire pulling device is mounted on the top of the rotor indexing device, and the winding device is mounted on one side of the rotor indexing device.

[0006] Preferably, the winding device includes a fixed base, an X-axis slide rail, an X-axis movable plate, a Y-axis slide rail, a Y-axis movable plate, a Z-axis slide rail, a Z-axis movable plate, and a winding head assembly. The fixed base is mounted on the equipment box, the X-axis slide rail is mounted on the fixed base, the X-axis movable plate is movably mounted on the X-axis slide rail, the Y-axis slide rail is mounted on the X-axis movable plate, the Y-axis movable plate is movably mounted on the top of the Y-axis slide rail, the Z-axis slide rail is mounted on the Y-axis movable plate, the Z-axis movable plate is movably mounted on the Z-axis slide rail, and the winding head assembly is mounted on the Z-axis movable plate.

[0007] Through the above technical solution, the slide rails of the X, Y, and Z axes, together with the movable plate, constitute a three-dimensional moving mechanism, enabling the winding head assembly to move precisely in three-dimensional space. This design allows the winding head assembly to precisely wind the rotor, meeting the winding requirements at different positions and angles, and ensuring the uniformity and consistency of the winding.

[0008] Preferably, the rotor indexing device includes a horizontal plate, a spindle positioner, an indexing positioner, and a linkage. The spindle positioner is mounted on the horizontal plate, the indexing positioner is mounted on the horizontal plate, and the linkage is mounted at the bottom of the horizontal plate and connected to the spindle positioner.

[0009] The above technical solution enables precise positioning and indexing control of the rotor during the winding process. The spindle positioner and the indexing positioner work together to not only meet the winding requirements, but also allow for quick material change after the winding is completed, thereby increasing production speed.

[0010] Preferably, the winding head assembly includes a rotor seat and a fly fork, the fly fork being annular in shape, and the rotor seat being disposed within the fly fork ring.

[0011] Through the above technical solution, the flying fork in the winding head assembly is designed as a ring, and the rotor seat is set inside the flying fork ring, making the winding process more stable and precise. The rotor seat can fit more tightly against the rotor, ensuring that the coil can be accurately aligned with the winding slot of the rotor during winding, reducing the risk of winding misalignment.

[0012] Preferably, the winding equipment is equipped with an anti-slip wire pulley frame, which is installed on the side of the Y-axis movable plate.

[0013] Through the above technical solution, the anti-slip reel frame effectively prevents the problem of wire jumping during the winding process. The anti-slip reel frame is installed on the side of the Y-axis movable plate, which can guide and stabilize the wire during the winding process, preventing the wire from deviating from the track due to inertia or vibration during high-speed winding.

[0014] Preferably, the spindle positioner is movably mounted on the side with a limit angle.

[0015] Through the above technical solution, the limiting angle can play a precise limiting role in the positioning process, ensuring that the rotor is placed in the winding equipment accurately. At the same time, the design of the limiting angle can effectively prevent the rotor from shifting due to vibration, offset and other factors during the winding process, thereby improving the winding accuracy and avoiding uneven winding.

[0016] Preferably, the spindle positioner includes two rotor supports, which are respectively arranged on opposite sides of the spindle positioner.

[0017] The above technical solution enables rapid material change after the main shaft rotates 180 degrees. This design allows the winding equipment to quickly move the next rotor to the working position simply by rotating the main shaft 180 degrees after completing the winding operation of one rotor, without waiting for a long time for manual material change or complex equipment adjustment, greatly improving production efficiency.

[0018] Preferably, the equipment box is equipped with a wire storage bin, and the top of the wire storage bin has a hole for the wire to pass through.

[0019] Through the above technical solutions, the design of the wire storage bin effectively solves the storage and supply needs of the winding equipment during high-speed operation, enabling the wire to be supplied to the winding head group in an orderly manner and avoiding the problem of wire tangling or accumulation.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] 1. This motor rotor winding mechanism rationally arranges key components such as the winding equipment, rotor indexing equipment, and wire pulling equipment, occupying a small space. The equipment box also includes a wire storage bin, which not only saves additional external wire storage space but also effectively protects the wire, making the entire device more compact. This compact structural design simplifies the overall layout of the equipment, facilitating equipment arrangement and process optimization in the production workshop.

[0022] 2. The motor rotor winding mechanism is highly flexible and can process rotors of different models. At the same time, the dual rotor frame design of the spindle positioner facilitates quick material change and meets the needs of mass production, enabling the equipment to be widely used in the production of different types of motors.

[0023] 3. The motor rotor winding mechanism has a high degree of automation. Manual work only involves loading and unloading, which improves production efficiency and winding accuracy. The highly automated design not only reduces the technical requirements for operators, but also reduces human error, making the equipment more suitable for efficient mass production.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0034] Please see Figures 1 to 2 This utility model provides a technical solution: a motor rotor winding mechanism, characterized in that:

[0035] A motor rotor winding mechanism includes a winding device 1, a rotor indexing device 2, a wire pulling device 3, and a device box 4. The winding device 1 is mounted on the device box 4, the rotor indexing device 2 is mounted on the device box 4, the wire pulling device 3 is mounted on the device box 4, the wire pulling device 3 is mounted on the top of the rotor indexing device 2, and the winding device 1 is mounted on one side of the rotor indexing device 2.

[0036] Specifically, the winding device 1 includes a fixed base 101, an X-axis slide rail 102, an X-axis movable plate 103, a Y-axis slide rail 104, a Y-axis movable plate 105, a Z-axis slide rail 106, a Z-axis movable plate 107, and a winding head assembly 108. The fixed base 101 is mounted on the equipment box 4, the X-axis slide rail 102 is mounted on the fixed base 101, the X-axis movable plate 103 is movably mounted on the X-axis slide rail 102, and the Y-axis slide rail 104 is mounted on the X-axis movable plate 103. The Y-axis movable plate 105 is movably mounted on top of the Y-axis slide rail 104, the Z-axis slide rail 106 is mounted on the Y-axis movable plate 105, the Z-axis movable plate 107 is movably mounted on the Z-axis slide rail 106, and the winding head assembly 108 is mounted on the Z-axis movable plate 107. The slide rails 102, 104, and 106 of the X, Y, and Z axes, together with the movable plates 103, 105, and 107, constitute a three-dimensional moving mechanism, enabling the winding head assembly 108 to move precisely in three-dimensional space. This design allows the winding head assembly 108 to precisely wind the rotor, meeting the winding requirements at different positions and angles, ensuring the uniformity and consistency of the winding. The modular design of the winding device 1 facilitates maintenance and adjustment, adapts to the winding needs of rotors of different specifications, and has strong adaptability and versatility, thus meeting diverse production needs.

[0037] Specifically, the rotor indexing device 2 includes a horizontal plate 201, a main spindle positioner 202, an indexing positioner 203, and a linkage 204. The main spindle positioner 202 and the indexing positioner 203 are both mounted on the horizontal plate 201. The linkage 204 is installed at the bottom of the horizontal plate 201 and is connected to the main spindle positioner 202. The main spindle positioner 202 is used for placing and changing materials, and also for positioning the materials. The indexing positioner 203 is used to rotate the rotor. The cable nozzle at the top of the indexing positioner 203 is retractable to drive the rotor to rotate. The linkage 204 is used to rotate the main spindle positioner 202, so that the main spindle positioners 202 can rotate synchronously and be in the same state.

[0038] Specifically, the winding head assembly 108 includes a rotor seat 109 and a fly fork 110. The fly fork 110 is annular, and the rotor seat 109 is positioned within the fly fork 110 ring, making the winding process more stable and precise. The rotor seat 109 can fit more tightly against the rotor, ensuring that the coil is accurately aligned with the winding slots of the rotor during winding, reducing the risk of winding misalignment. This design improves winding quality while also reducing equipment maintenance requirements. Due to its simple structural design, low failure rate, and easier maintenance and debugging, the operating cost of the equipment is reduced.

[0039] Specifically, the winding device 1 is equipped with an anti-slip reel frame 111, which is installed on the side of the Y-axis movable plate 105. The anti-slip reel frame 111 effectively prevents wire slippage during winding. Installed on the side of the Y-axis movable plate 105, the anti-slip reel frame 111 guides and stabilizes the wire during winding, preventing it from deviating from the track due to inertia or vibration during high-speed winding. This design significantly reduces defects such as wire slippage and tangling during winding, thereby ensuring winding accuracy and consistency.

[0040] Specifically, the spindle positioner 202 has a movably mounted limiting angle 205 on its side. The limiting angle 205 provides precise positioning during the winding process, ensuring the rotor's accurate placement within the winding equipment 1. Simultaneously, the limiting angle 205 effectively prevents rotor displacement due to vibration, offset, or other factors during winding, thereby improving winding accuracy and preventing uneven winding. The movable mounting of the limiting angle 205 allows for fine-tuning according to different rotor sizes and specifications, increasing the equipment's applicability and flexibility. This design not only facilitates adjustment and maintenance but also adapts to the production needs of different types of rotors.

[0041] Specifically, the spindle positioner 202 includes two rotor frames 206, which are respectively set on opposite sides of the spindle positioner 202. The spindle can quickly change materials after rotating 180 degrees. The setting of two rotor frames 206 means that when one rotor is performing a winding operation, the rotor frame 206 on the other side can complete the preparation work in advance to achieve continuous operation.

[0042] Specifically, the equipment box 4 is equipped with a wire storage bin 401 inside, and the top of the wire storage bin 401 has a hole for the wire to pass through. The wire storage bin 401 is set inside the equipment box 4, which not only saves space, but also protects the wire from the influence of the external environment, such as dust and moisture, thereby extending the service life of the wire. At the same time, it solves the storage and supply needs of the winding equipment 1 during high-speed operation, so that the wire can be supplied to the winding head group 108 in an orderly manner, avoiding the problem of wire tangling or accumulation.
