Description

Technical Field

[0001] The invention relates to the technical field of motors, in particular to motor coil winding equipment. Background Art

[0002] The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. It uses the energized coil to generate a rotating magnetic field, which then acts on the rotor to form a magneto-electrical torque, thereby rotating the motor. The motor winding coil winding equipment is a key equipment in the motor manufacturing process. It is mainly used to accurately wind the wire on the stator or rotor of the motor to form a winding. These equipment usually include winding machines, can winding machines, coil wire cutting machines, etc.

[0003] However, the existing motor winding coil equipment relies on manual operation or simple mechanical structure to complete the winding work, which not only increases the labor cost, but also limits the production speed. At the same time, when the equipment winds a winding with too many turns, the arrangement of the winding coil is often relatively tight, resulting in limited heat dissipation channels and difficulty in effectively dissipating heat. The gap between the winding and the stator is small, which reduces the convection and radiation space of heat. The messy gap will lead to an increase in harmonic content and affect the utilization efficiency of the magnetic field. In addition, the existing motor coil winding equipment can usually only wind a single motor and cannot be integrated with an assembly line or other production lines with a high degree of automation. The low automation increases production costs and labor requirements. At the same time, some motors are wound in parallel with two wires, and the equipment that can process motors with two-wire windings is usually more complex in structure and has a higher design cost. This not only increases the purchase cost and maintenance difficulty of the equipment, but may also limit its scope of application and flexibility. Summary of the invention

[0004] (I) Technical problems to be solved: In view of the deficiencies in the prior art, the present invention provides a motor coil winding device, which has the advantages of being able to perform periodic tightening and loosening of motor winding coils, having a high degree of automation, a simple structure, and being able to process double-wire parallel coils at low cost. This solves the problem that the winding coils wound by the existing motor coil winding device have poor heat dissipation effect, are not suitable for production line processes, and have a high cost for processing double-wire parallel coils.

[0005] (II) Technical solution: In order to achieve the purpose of the above-mentioned motor winding coil being able to perform periodic tightening and loosening winding with high automation and simple structure and being able to process double-wire parallel winding coils at low cost, the present invention provides the following technical solution: a motor coil winding device, comprising a stator clamp and a winding rod, wherein the stator clamp is symmetrically arranged up and down, and a motor stator is fixedly arranged between the stator clamps symmetrically arranged up and down, the winding rod is arranged on one side of the motor stator in the winding direction, the winding rod is L-shaped, and a rotating shaft is fixedly connected to the winding rod, a sliding rod is connected above the stator clamp, and one end of the sliding rod is slidably connected to a linear guide rail, and the linear guide rail is arranged perpendicularly to the rotating shaft. The rotating shaft can move relative to a direction perpendicular to the linear guide rail; a copper wire is arranged on the winding rod, and one end of the copper wire is fixedly connected to the motor stator; when the copper wire is wound, the rotating shaft drives the winding rod to rotate coaxially, and at the same time, the linear guide rail and the sliding rod drive the motor stator to rotate with the rotating shaft as the axis, the rotation radius of the motor stator is greater than zero and smaller than the radius of the winding rod, the rotation speed of the motor stator is smaller than the rotation speed of the winding rod, and the motor stator and the winding rod rotate alternately.

[0006] Preferably, the winding rod includes a long winding rod and a short winding rod, the long winding rod and the short winding rod are arranged at 180° between each other, the short L-shaped end of the long winding rod is longer than the short L-shaped end of the short winding rod, the long winding rod and the short winding rod are both provided with the copper wire, and the copper wire on the long winding rod and the copper wire on the short winding rod are both wound around the stator of the motor.

[0007] Preferably, the long winding rod and the short winding rod are both provided with wire grooves, and the wire grooves are connected to the rotating shaft and penetrate the rotating shaft axially along the rotating shaft.

[0008] Preferably, the stator clamps are arranged in several groups along the direction of the linear guide rail.

[0009] Preferably, a push rod is also slidably arranged in the axis of the rotating shaft, and the push rod passes through the rotating shaft. An annular push plate is fixedly arranged on the push rod on one side of the winding rod, and the radius of the push plate is smaller than the radius of the winding rod. When the push rod slides relative to the rotating shaft, the push plate pushes the copper wire to move axially along the rotating shaft.

[0010] Preferably, the rotating shaft is connected to a driving module that drives it to rotate and move forward and backward.

[0011] Preferably, the sliding rod is connected to the linear guide rail via a slider, and a rotating motor for driving the sliding rod to rotate is fixedly provided on the slider, and when the sliding rod rotates, the stator clamp and the motor stator are driven to rotate together.

[0012] Preferably, the shape of the stator fixture matches the shape of the end face of the motor stator.

[0013] (III) Beneficial effects: Compared with the prior art, the present invention provides a motor coil winding device, which has the following beneficial effects: 1. In the motor coil winding device, through the combined use of the winding rod structure, the sliding rod structure, the slider structure, and the linear guide rail structure, during the winding process of the device, through the up-and-down telescoping of the sliding rod and the left-and-right sliding of the slider on the linear guide rail, the motor stator rotates in a circular motion with a rotation radius greater than zero around the rotation axis. During the rotation of the motor stator, an interleaved motion is formed with the winding rod. This interleaved motion enables the wound copper wire to form a periodic tightening and loosening change. The size of the period is determined by the differential speed between the motor stator and the winding rod. The larger the differential speed, the larger the period; the smaller the differential speed, the smaller the period. This change forms regular tiny gaps between the copper wires and between the copper wires and the stator winding. These gaps can serve as heat dissipation channels during the operation of the motor, promoting heat transfer and dissipation, thereby reducing the working temperature of the winding. Moreover, by adjusting the tightening and loosening of the period, the position and shape of the winding can be changed, optimizing the distribution of the magnetic field in the stator, improving the utilization efficiency of the magnetic field. At the same time, this periodic tightening and loosening design can also reduce the electromagnetic field distortion caused by uneven winding distribution, thereby reducing the harmonic content generated by the winding.

[0014] 2. In the motor coil winding device, through the combined use of the slider structure and the linear guide rail structure, whenever a motor stator is completed with winding, the device can automatically move the wound motor stator away through the cooperation of the linear guide rail and the slider, and move the next motor stator to be wound to the position of the winding rod. This process is automated and does not require manual intervention, thus improving the working efficiency of the winding device. Therefore, the device can be easily integrated with the motor stator processing assembly line. This modular design enables the device to easily adapt to different production environments and requirements, and is also convenient for device maintenance and upgrade. In addition, when used in cooperation with the assembly line, it can greatly improve the automation level of the entire production line, thereby improving production efficiency and product quality.

[0015] 3. In the motor coil winding device, through the combined use of the long winding rod structure and the short winding rod structure, during the rotation process, two overlapping copper coils will be formed on the motor stator winding for winding. Therefore, it can achieve double-wire parallel winding of the motor stator winding, and its own structure is simple and can flexibly adapt to the requirements of different specifications and types of motor stator windings.

[0016] 4. The motor coil winding equipment uses a winding rod structure and a push plate structure in combination. During the process of the winding rod winding the copper wire, the push rod can be controlled to move forward and backward so that the surface of the push plate contacts the copper wire in the winding process. When in contact, the push plate will generate an axial thrust on the copper wire, so that the winding position of the copper wire on the motor stator winding changes, so that the copper wire can be wound more accurately according to the predetermined path and position. Since the push plate can fine-tune the copper wire, it can significantly improve the accuracy of the equipment in the process of winding the copper wire, so that the copper wire can be tightly wound on the winding in a predetermined manner, avoiding the problems of local accumulation and gaps.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-6, a motor coil winding device, including a stator clamp 1 and a winding rod 7, wherein the stator clamp 1 is symmetrically arranged up and down, and the stator clamp 1 is symmetrically arranged up and down mainly to firmly clamp the motor stator 2, and ensure that the motor stator 2 will not shake or deviate during the winding process. The motor stator 2 is fixedly arranged between the stator clamps 1 arranged symmetrically up and down, and a sliding rod 3 is connected above the stator clamp 1, and one end of the sliding rod 3 is slidably connected to a linear guide 6, and the sliding rod 3 is connected to provide a driving force so that the motor stator 2 can move and adjust in the vertical direction. The linear guide 6 is slidably connected above the sliding rod 3 to guide the motor stator 2 to move and adjust in the horizontal direction. A winding rod 7 is arranged on one side of the motor stator 2 in the winding direction, and the winding rod 7 is L-shaped, and a rotating shaft 11 is fixedly connected to the winding rod 7. The winding rod 7 is arranged on one side of the motor stator 2 in the winding direction to facilitate winding the copper wire 10 on the winding of the motor stator 2. The winding rod 7 is designed in an L-shape, which can conveniently guide the copper wire 10 to be wound along a predetermined path. The linear guide 6 is vertically arranged between the rotating shaft 11. This structure enables the motor stator 2 to be adjusted in both horizontal and vertical directions. The rotating shaft 11 can move relative to the direction perpendicular to the linear guide 6. The rotating shaft 11 can move relative to the direction perpendicular to the linear guide 6 so that it can move forward and backward as needed during the winding process, thereby changing the winding position and path of the copper wire 10; the copper wire 10 is arranged on the winding rod 7, and one end of the copper wire 10 is fixedly connected to the motor stator 2. The copper wire 10 is arranged on the winding rod 7 so that the copper wire 10 is wound around the winding of the motor stator 2. One end of the copper wire 10 is fixedly connected to the motor stator 2 to ensure that the copper wire 10 will not fall off or deviate from the predetermined path during the winding process; please refer to Figure 5 , Figure 6 , Figure 7 When winding the copper wire 10, the rotating shaft 11 drives the winding rod 7 to rotate coaxially, and at the same time, the linear guide 6 and the sliding rod 3 drive the motor stator 2 to rotate around the rotating shaft 11. This design allows the motor stator 2 to maintain dynamic adjustment during the winding process, ensuring that the copper wire 10 can be wound along a predetermined path. This rotational movement combined with the movement of the winding rod 7 can optimize the winding speed and accuracy. Figure 7 As shown, Figure 7 The dotted line indicates the rotation of the motor stator 2, and the rotation radius of the motor stator 2 is greater than zero, the rotation speed of the motor stator 2 is less than the rotation speed of the winding rod 7, and the motor stator 2 rotates alternately with the winding rod 7. The alternate rotation increases the winding tension of the copper wire 10, making it fit tightly on the stator winding, thereby improving the tightness and stability of the winding and reducing gaps and overlaps.

[0027] See also Figure 3 , Figure 5 and Figure 6The winding rod 7 includes a long winding rod 8 and a short winding rod 9, and the long winding rod 8 and the short winding rod 9 are arranged at 180°. This design is to achieve double-wire parallel winding and improve winding efficiency and tightness. The 180° arrangement allows the two copper wires 10 to alternately overlap on the winding, thereby enhancing the electrical performance and mechanical stability of the winding. The L-shaped short end of the long winding rod 8 is longer than the L-shaped short end of the short winding rod 9. The long winding rod 8 and the short winding rod 9 are both provided with copper wires 10, and the copper wires 10 on the long winding rod 8 and the copper wires 10 on the short winding rod 9 are both wound on the motor stator 2. The design of double-wire parallel winding can speed up the winding speed, improve the density and electrical conductivity of the winding, and meet the requirements of different motor specifications. The long winding rod 8 and the short winding rod 9 are both provided with wire grooves, which are connected to the rotating shaft 11 and penetrate the rotating shaft 11 axially along the rotating shaft 11. The wire trough is designed to reasonably guide and manage the path of the copper wire 10, prevent the copper wire 10 from being knotted, overlapped or broken during high-speed winding, and improve the reliability and stability of equipment operation.

[0028] See also Figure 1-5, the stator clamp 1 is provided with several groups along the direction of the linear guide rail 6. This design enables the equipment to continuously process multiple motor stators 2, thereby improving production efficiency. Multiple clamps can prepare multiple stators at the same time, realize assembly line operation, and reduce waiting time. A push rod 12 is also slidably arranged in the axis of the rotating shaft 11, and the push rod 12 runs through the rotating shaft 11. The design of the push rod 12 allows the position of the copper wire 10 to be accurately adjusted during the winding process. The sliding of the push rod 12 can change the position of the push plate 13, thereby affecting the winding path of the copper wire 10 on the stator. An annular push plate 13 is fixedly arranged on the push rod 12 on one side of the winding rod 7. The push plate 13 can apply a uniform thrust to the copper wire 10 during the winding process to ensure that the copper wire 10 fits tightly on the stator winding. The annular design can effectively distribute force and prevent the copper wire 10 from tying or loosening. The radius of the push plate 13 is smaller than the radius of the winding rod 7. This design ensures that the push plate 13 only contacts the copper wire 10 without interfering with the operation of the winding rod 7. The smaller radius can effectively adjust the position of the copper wire 10 in a limited space. When the push rod 12 slides relative to the rotating shaft 11, the push plate 13 pushes the copper wire 10 to move axially along the rotating shaft 11. This design can achieve precise control of the winding of the copper wire 10, and the winding position is changed by axial movement, thereby improving the accuracy and consistency of the winding. The rotating shaft 11 is connected to a drive module that drives it to rotate and move back and forth, which is not shown in the figure. This drive module provides comprehensive control over the movement of the winding rod 7, ensuring that the equipment can adjust the winding speed and position as needed, improving the flexibility of operation and the quality of winding. The sliding rod 3 is connected to the linear guide 6 through a slider 4, and a rotating motor 5 that drives the sliding rod 3 to rotate is also fixed on the slider 4. When the sliding rod 3 rotates, the stator fixture 1 and the motor stator 2 are driven to rotate together. The shape of the stator fixture 1 matches the shape of the end face of the motor stator 2. The matching fixture shape ensures that the stator can be firmly fixed to prevent displacement or vibration during the winding process.

[0029] Working principle: fix the motor stator 2 by means of a stator clamp 1 symmetrically arranged up and down, and adjust its position by means of a sliding rod 3 and a slider 4 so that it is placed at the position of a winding rod 7, connect the copper wire 10 on the winding rod 7 to the winding on the motor stator 2, and after fixation, start the driving module to drive the rotating shaft 11 to drive the winding rod 7 to rotate, and during the rotation, move the winding rod 7 back and forth so that the copper wire 10 is wound on the winding of the motor stator 2 according to a predetermined winding direction and number of windings. During the winding process, the sliding rod 3 is extended and retracted up and down and the slider slides left and right on the linear guide rail 6, so that the motor stator 2 makes a circular rotation with a rotation radius greater than zero around the rotating shaft 11 as the axis, wherein the rotation radius is specifically set according to the size of the motor stator 2 and the radius of the winding rod 7, and its rotation radius is smaller than the radius of the winding rod 7. The motor stator 2 forms a staggered motion with the winding rod 7 during the movement. At the same time, since the rotation speed of the winding rod 7 is much greater than the rotation speed of the motor stator 2, this staggered motion can apply a dynamic tension to the copper wire 10 during the winding process, so that the copper wire 10 on one side of the motor stator 2 winding is tightened during the rotation process, while the copper wire 10 on the other side is relaxed, so that the wound copper wire 10 forms a periodic tightening and relaxing change, wherein the period size is determined by the differential speed of the motor stator 2 and the winding rod 7, the larger the differential speed, the larger the period, and the smaller the differential speed, the smaller the period. By controlling the rotation speed of the winding rod 7, the rotation radius and the rotation speed of the motor stator 2, accurate control of the tension can be achieved, thereby ensuring that the copper wire 10 can be tightly wound on the winding in a predetermined manner. The periodic tightening and loosening of the copper wire 10 can provide more uniform heat dissipation, which helps to quickly dissipate heat, thereby reducing the operating temperature of the winding. When the copper wire 10 is tightened, it fits tightly on the motor stator 2 winding to form a tight contact surface, which helps to transfer the heat generated inside the winding to the copper wire 10 by heat conduction. When the copper wire 10 is relaxed, the gap between it and the motor stator 2 winding increases, forming a space for heat dissipation. Since this space is uniform, it allows heat to be more easily dissipated from the winding surface to the surrounding environment by thermal convection and radiation. In addition, the periodic changes in tightness can also reduce the thermal stress generated by the long-term tight fit of the copper wire 10 to a certain extent, thereby extending the service life of the copper wire and the entire motor. In addition, by adjusting the periodic tightening and relaxation, the position and shape of the winding can be changed, the distribution of the magnetic field in the stator can be optimized, and the utilization efficiency of the magnetic field can be improved. At the same time, this periodic tightening and relaxation design can also reduce the electromagnetic field distortion caused by uneven distribution of the winding, thereby reducing the harmonic content generated by the winding.

[0030] Whenever a winding is wound, the rotating motor 5 on the slider 4 drives the sliding rod 3 to rotate, thereby driving the motor stator 2 to rotate, so that the windings in other directions that are not wound with the copper wire 10 are wound.

[0031] Whenever a motor stator 2 is wound, the device can automatically remove the motor stator 2 that has been wound and move the next motor stator 2 to be wound to the position of the winding rod 7 through the cooperation of the linear guide 6 and the slider 4. This process is automated and does not require human intervention, thereby improving the working efficiency of the winding equipment. Therefore, the device can be easily integrated with the motor stator 2 processing line. It is only necessary to connect the linear guide 6 to the corresponding position on the assembly line to realize the automatic operation of the equipment on the assembly line. This modular design allows the device to easily adapt to different production environments and requirements, and is also convenient for the maintenance and upgrading of the equipment. In addition, the device has a high degree of automation, and when used in conjunction with the assembly line, it can greatly improve the automation level of the entire production line, thereby improving production efficiency and product quality.

[0032] The winding rod 7 is set as a long winding rod 8 and a short winding rod 9, and the copper wire 10 is set on the long winding rod 8 and the short winding rod 9 to wind the winding on the motor stator 2. During the winding process, since the long winding rod 8 and the short winding rod 9 are set at 180 degrees, when the long winding rod 8 and the short winding rod 9 are rotating, the copper wire 10 will form two groups of overlapping copper wire 10 circles on the motor stator 2 winding for winding, so that the double-wire parallel winding of the motor stator 2 winding can be realized, and the structure itself is simple and can flexibly adapt to the requirements of motor stator 2 windings of different specifications and types. At the same time, when this double-wire parallel winding

[0033] During the process of winding the copper wire 10 by the winding rod 7, the push rod 12 can be controlled to move forward and backward so that the surface of the push plate 13 contacts the copper wire 10 during the winding process. When in contact, the push plate 13 will generate an axial thrust on the copper wire 10, so that the winding position of the copper wire 10 on the motor stator 2 winding changes, so that the copper wire 10 can be wound more accurately according to the predetermined path and position. Since the push plate 13 can fine-tune the copper wire 10, it can significantly improve the accuracy of the equipment during the process of winding the copper wire 10. Thereby, the copper wire 10 is tightly wound on the winding in a predetermined manner, avoiding the problems of local accumulation and gaps.
