Description

Technical Field

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

[0002] The existing stator coil winding equipment is a device specially used in the motor manufacturing process. In the production of the motor stator, the stator coil needs to be wound according to a specific winding method, and the coil needs to be pressed after the winding is completed.

[0003] In a Chinese patent with patent publication number CN115818349A, a winding device for producing a generator stator coil is disclosed, comprising: a workbench, on which a winding mechanism, a guiding mechanism, and a stabilizing mechanism are arranged, the winding mechanism comprising a frame, a double-headed motor, a threaded rod, a movable plate, a base, a driving motor, a first rotating rod, a movable rod, and a clamping plate, the frame is fixedly connected to the top of the workbench, the double-headed motor is fixedly installed at the bottom of the inner wall of the frame, one end of the threaded rod is fixedly connected to the coupling of the double-headed motor, and the other end of the threaded rod is rotatably connected to the inner wall of the frame through a first bearing.

[0004] However, the prior art and the equipment in the prior art documents still have the following defects when used specifically: 1. Compared with the winding method in the prior art, before the stator coil is wound, in order to ensure the consistency of the winding coil, the tension of the copper wire has been adjusted and kept constant. During the winding process, the stator coil needs to move back and forth on the workbench. During this process, when the stator coil moves toward the winding turntable, the distance between the stator coil and the winding turntable will gradually decrease, which is equivalent to the copper wire's stretchable space becoming smaller. The original tension of the copper wire is set based on a larger stretching space. At this time, under the adjusted tension, the copper wire will not be able to maintain its original taut state due to the smaller stretchable space, resulting in a decrease in tension and an overall loose state, which in turn causes the copper wire to be unable to fit tightly on the skeleton of the stator coil, making the spacing between each layer uneven, causing the copper wire to collapse in certain areas.

[0005] 2. In the process of stator coil winding, the winding operation is carried out in steps. First, the winding work will be carried out on half of the coil. When only half of the coil is wound at high speed, the winding equipment will exert force on the half of the coil being wound. This force will cause the entire stator coil system to vibrate, and the other half of the coil that is not wound is in a relatively free state because there is no constraint from the winding force. Therefore, when it is subjected to the vibration excitation transmitted from the winding part, it will generate acceleration according to its own mass and cause jitter. This jitter phenomenon will affect the symmetry and regularity of the coil. In high-precision motors, this irregular winding distribution will also affect the magnetic field distribution inside the motor, thereby reducing the performance of the motor.

[0006] 3. For the equipment in the existing documents, when winding the electronic coils, it is still preferred for the staff to do manual operation. This manual operation mainly includes the following three steps: first, multiple coils to be wound are installed in sequence, second, the installation stability is checked after the installation is completed, and finally, the staff are required to take them out in sequence after the winding is completed. From the perspective of work efficiency, in large-scale production, a large number of electronic coils need to be installed and wound. It is difficult to complete a large number of tasks in a short time by relying entirely on manual operation, which in turn cannot meet the efficiency requirements of large-scale production. From the perspective of quality control, manual operation is difficult to ensure a high degree of consistency. Manual operation is easily affected by subjective factors such as fatigue and emotions. Mistakes will occur during the winding process or when taking out the coils, thereby affecting the winding quality of the electronic coils and increasing the defective rate.

[0007] In view of this, the present invention proposes a motor stator coil winding clamping device to make up for and improve the deficiencies of the prior art. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a motor stator coil winding clamping device to solve the technical problems raised in the above background technology.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is: a motor stator coil winding clamping device, used for winding a stator module, comprising a winding machine body, an operating table is installed on the front side of the winding machine body, a control base is installed on the upper surface of the operating table, a coil assembly is installed above the control base, a symmetrical winding mechanism is arranged above the operating table, and a tension balancing mechanism is arranged inside the operating table; the symmetrical winding mechanism is used to quickly release the stator module and ensure the symmetrical balance of the winding; the tension balancing mechanism is used to synchronously adjust the height of the stator module during winding to ensure the tightness of the winding.

[0010] Furthermore, the symmetrical winding mechanism includes a slide plate group slidably connected to the front side of the stator module, the lower surface of the slide plate group is evenly fixedly connected with a trigger cover, the upper surface of the control base is evenly fixedly connected with a vertical sliding shaft, the outer wall of the vertical sliding shaft is slidably connected with a limited support plate, the outer wall of the vertical sliding shaft is threadedly connected with an adjustment dial, and fitting gaskets are evenly installed above the adjustment dial, the outer walls of the fitting gaskets are fixedly connected with a horizontal sliding shaft, and the upper surface of the adjustment dial is rotatably connected with a buffer bin.

[0011] Furthermore, the trigger cover and the limiting support plate are both in the same vertical plane, the trigger cover corresponds to the top of the vertical sliding shaft, and the limiting support plate is provided with a right-angle groove at the position corresponding to the fitting gasket, and the limiting support plate and the fitting gasket are slidably connected through the right-angle groove.

[0012] Furthermore, a threaded groove is provided on the outer wall of the lower half of the vertical sliding shaft, and a ball screw structure is formed between the vertical sliding shaft and the adjusting turntable.

[0013] Furthermore, bending grooves are evenly penetrated at positions on the surface of the adjusting dial corresponding to the fitting gasket, and the adjusting dial and the fitting gasket are rotationally connected via the bending grooves.

[0014] Furthermore, the fitting gasket as a whole is composed of a combination of no less than four resistance pads, and each two of the four resistance pads form a group, and the side walls of a group of resistance pads in the fitting gasket located in front of the limiting support plate are all installed with corrugated protrusions, and the side walls of a group of resistance pads in the fitting gasket located behind the limiting support plate are all opened with corrugated grooves.

[0015] Furthermore, the horizontal sliding shaft and the fitting gasket are kept perpendicular to each other, the buffer bin is provided with a circular hole at a position corresponding to the horizontal sliding shaft, and the interior of the buffer bin is filled with rigid foam polyurethane.

[0016] Furthermore, the tension balancing mechanism includes an auxiliary base evenly and fixedly connected to the inside of the operating table, and a ball bearing is evenly and rotatably connected to the inside of the auxiliary base, and a roller buckle is installed above the ball bearing.

[0017] Furthermore, the auxiliary base is in the shape of an inclined triangle as a whole, the height of the inclined surface of the auxiliary base is equal to the winding distance in the stator module, and the roller buckle is initially located at the lowest inclined surface of the auxiliary base.

[0018] Furthermore, the roller buckles are rotatably connected to the lower surface of the vertical sliding shaft, the roller buckles are divided into inner and outer layers, the size of the outer layer of the roller buckle is equal to twice the size of the inner layer, and the inner and outer layers of the roller buckle are movably connected through a spring.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) In order to solve the problem of loose copper wire tension in the prior art, the present device uses the auxiliary base in the tension balancing mechanism in conjunction with the automatic reciprocating displacement during winding to dynamically adjust the winding height of the stator module, that is, the stator module is raised when it approaches the winding turntable and lowered when it moves away. This winding method ensures that the copper wire can always remain taut during output, effectively avoiding tension fluctuations caused by changes in the copper wire's stretchable space. Relying on this constant tension control not only improves the tightness of the copper wire winding, making the spacing between each layer of copper wire more uniform, but also significantly enhances the tightness of the copper wire fitting on the stator coil frame, thereby improving the winding quality.

[0020] Compared with the winding method in the prior art, this device dynamically adjusts the winding height of the stator module and no longer relies on a single tension adjustment device to maintain the taut state of the copper wire, thereby enabling the equipment to adapt to different winding conditions. Regardless of whether the stator coil moves at a fast speed or the winding path is more complicated, it can ensure that the copper wire always maintains appropriate tension.

[0021] Among them, this device greatly reduces the contact area between the roller buckle and the auxiliary base through the point contact between the two, making the roller buckle move more smoothly and reducing the vibration caused by friction fluctuations. The smaller friction means that the energy loss of the equipment drive during movement is reduced, thereby improving the energy utilization efficiency of the device. In addition, the reduction in friction can significantly reduce the wear of the roller buckle and the auxiliary base, extend their service life, thereby reducing the frequency of component replacement and reducing maintenance costs.

[0022] (2) For the use scenario where the device is winding at a high speed and the stator module load is gradually increasing, the device divides the roller buckle into an inner and outer layer and movably connects them through a spring, which has the following advantages: First, the size of the outer roller buckle is equal to twice the size of the inner layer. This size design increases the contact area between the outermost wall of the roller buckle and the auxiliary base, thereby improving the stability and support capacity during the winding process. During the high-speed winding process, the larger contact area can more effectively disperse the load, reduce the situation where a single point is subjected to excessive force, and help prevent the roller buckle from being damaged due to uneven force.

[0023] Second: The inner and outer layers are movably connected by springs, which gives the roller buckle good overall adaptability. As the winding progresses, the load borne by the stator module becomes larger and larger. The spring connection can allow the inner and outer roller buckles to produce a certain relative displacement when subjected to force, thereby absorbing part of the impact and vibration, protecting the roller buckle and the stator module from vibration, and ensuring stability and accuracy during the winding process by maintaining close contact between the roller buckle and the stator module.

[0024] (3) In order to improve the problem of force vibration of the stator module during the winding process, the device achieves self-locking of the stator module by shrinking and moving the fitting gasket during the winding process to keep it stable, thereby improving the vibration resistance of the stator module during the winding process, helping to reduce the coil jitter caused by vibration, and helping to improve the winding accuracy through a stable winding method, so that the winding can be carried out according to a predetermined pattern, thereby improving the symmetry and regularity of the coil.

[0025] Compared with the traditional winding process, the regularity of the winding is improved after the stator module is self-locked and stabilized by fitting the gasket. When the product is in later use, the regular coil winding can make the magnetic field distribution generated by the current more uniform and symmetrical, reducing the magnetic field disturbance caused by irregular winding shape, thereby improving the overall performance of the motor product.

[0026] What is particularly important is that the device divides the fitting gaskets into two groups and designs them on the front and rear sides of the stator module. The setting of corrugated protrusions and corrugated grooves enables subtle differences in the process of locking the stator module. The corrugated protrusions increase the friction between the fitting gasket and the unwound side of the stator module. This method of precisely controlling the friction effectively prevents the phenomenon of continuous vibration on the unwound side of the stator module, thereby enhancing the overall vibration resistance of the stator module.

[0027] Among them, when the gasket is shrunk and fitted, the horizontal sliding shaft is synchronously moved to the inside of the buffer bin, and the characteristic of rigid foam polyurethane that hardens under stress is used to provide buffering, so that the device can effectively resist the impact force generated by high-speed winding, thereby reducing the dynamic stress on the device components and reducing the accumulation of fatigue damage.

[0028] (4) This device can quickly lock and unlock multiple stator modules for replacement simply by pressing the slide plate group back and forth. It can process more stator modules per unit time, thereby improving the production rhythm of the entire electronic coil winding process and meeting the efficiency requirements of large-scale production. This one-button operation method helps to improve the degree of automation of the production process and greatly reduces the links of manual intervention, which can then be better integrated with other automated equipment or processes to achieve the continuity and efficiency of the entire production process.

[0041] 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.

[0042] It should be noted that the winding machine body 1, operating table 11, control base 12, coil assembly 13, stator module 14 and other components can adopt commercially available related products. The structure and working principle of these products belong to the existing technology and will not be repeated here.

[0043] Example 1: Please refer to Figure 1 and Figure 2As shown, a motor stator coil winding clamping device is used for winding a stator module 14, including a winding machine body 1, an operating table 11 is installed on the front side of the winding machine body 1, a control base 12 is installed on the upper surface of the operating table 11, a coil assembly 13 is installed above the control base 12, a symmetrical winding mechanism 2 is arranged above the operating table 11, and a tension balancing mechanism 3 is arranged inside the operating table 11.

[0044] As an existing mature technology, the coil assembly 13 is specifically composed of components such as a tensioner, a wire clamp, a winding turntable and scissors.

[0045] Please refer to Figures 3 to 8 As shown, the symmetrical winding mechanism 2 includes a slide plate group 21 slidably connected to the front side of the stator module 14, the lower surface of the slide plate group 21 is evenly fixedly connected with a trigger cover 22, the upper surface of the control base 12 is evenly fixedly connected with a vertical sliding shaft 24, the outer wall of the vertical sliding shaft 24 is slidably connected with a limited support plate 23, the outer wall of the vertical sliding shaft 24 is threadedly connected with an adjusting dial 25, and a fitting gasket 26 is evenly installed above the adjusting dial 25, the outer wall of the fitting gasket 26 is fixedly connected with a horizontal sliding shaft 27, and the upper surface of the adjusting dial 25 is rotatably connected with a buffer bin 28.

[0046] It should be noted that the trigger cover 22 and the limit support plate 23 are both in the same vertical plane, the trigger cover 22 corresponds to the top of the vertical sliding shaft 24, and the limit support plate 23 is provided with a right-angle groove at the position corresponding to the fitting gasket 26, and the limit support plate 23 and the fitting gasket 26 are slidingly connected through the right-angle groove, and a threaded groove is provided on the outer wall of the lower half of the vertical sliding shaft 24, and a ball screw structure is formed between the vertical sliding shaft 24 and the adjusting dial 25, and the surface of the adjusting dial 25 corresponding to the position of the fitting gasket 26 is evenly provided with bending grooves, and the adjusting dial 25 and the fitting gasket 26 are rotationally connected through the bending grooves.

[0047] Specifically, when the stator modules 14 are placed one by one outside the limit support plate 23, the staff presses the slide plate group 21 downward, and the trigger cover 22 will synchronously squeeze the vertical sliding shaft 24 downward. Since the structure between the vertical sliding shaft 24 and the adjusting dial 25 is similar to the ball screw structure, and the pitch of the vertical sliding shaft 24 is equal to the inner diameter of the adjusting dial 25, and the angle between the external thread of the vertical sliding shaft 24 and the tangent of the internal cylinder of the adjusting dial 25 and the horizontal plane is greater than 45 degrees, when the vertical sliding shaft 24 moves downward, the vertical downward squeezing force can be smoothly transmitted to the inside of the adjusting dial 25, thereby driving it to rotate. During the rotation of the disk 25, the curved grooves running through its surface will continuously squeeze the outer wall of the fitting gasket 26, thereby driving the fitting gasket 26 to shrink and move along the right-angle grooves on the surface of the limiting support disk 23. The fitting gasket 26 shrinks and moves during the winding process to achieve self-locking of the stator module 14 and keep it stable, thereby improving the vibration resistance of the stator module 14 during the winding process, helping to reduce the coil jitter caused by vibration, and helping to improve the winding accuracy through a stable winding method, so that the winding can be carried out according to a predetermined pattern, thereby improving the symmetry and regularity of the coil.

[0048] It should be noted that the fitting gasket 26 as a whole is composed of a combination of no less than four resistance pads, and each two of the four resistance pads form a group. The side walls of a group of resistance pads in the fitting gasket 26 located in front of the limiting support plate 23 are all installed with corrugated protrusions, and the side walls of a group of resistance pads in the fitting gasket 26 located behind the limiting support plate 23 are all provided with corrugated grooves.

[0049] Specifically, the fitting gasket 26 is divided into two groups and designed on the front and rear sides of the stator module 14. The arrangement of the corrugated protrusions and the corrugated grooves enables subtle differences to be achieved in the process of locking the stator module 14. The corrugated protrusions increase the friction between the fitting gasket 26 and the unwound side of the stator module 14. This precise control of the friction effectively prevents the phenomenon of continuous vibration of the unwound side of the stator module 14, thereby enhancing the overall vibration resistance of the stator module 14.

[0050] It should be noted that the horizontal sliding shaft 27 and the fitting gasket 26 are kept perpendicular to each other, and the buffer bin 28 is provided with a circular hole at the position corresponding to the horizontal sliding shaft 27, and the interior of the buffer bin 28 is filled with rigid foam polyurethane.

[0051] Specifically, when the fitting gasket 26 contracts and moves, the horizontal sliding shaft 27 that is perpendicular to it will also move synchronously. When the fitting gasket 26 stops moving, the horizontal sliding shaft 27 just moves to the inside of the buffer bin 28 and contacts with the rigid foam polyurethane filled inside it. The rigid foam polyurethane hardens under stress and provides a buffer, so that the device can effectively resist the impact force generated by high-speed winding, thereby reducing the dynamic stress on the device components and reducing the accumulation of fatigue damage.

[0052] Example 2: Based on Example 1, please refer to Figures 9 to 11 As shown, the tension balancing mechanism 3 includes an auxiliary base 31 evenly fixedly connected to the inside of the operating table 11, and a ball member 32 is evenly rotatably connected inside the auxiliary base 31, and a roller buckle 33 is installed above the ball member 32.

[0053] It should be noted that the auxiliary base 31 is an inclined triangle as a whole, the inclined height of the auxiliary base 31 is equal to the winding distance in the stator module 14, and the roller buckle 33 is initially located at the lowest inclined surface of the auxiliary base 31, and the roller buckle 33 is rotatably connected to the lower surface of the vertical sliding shaft 24. The roller buckle 33 is divided into an inner and outer double layer, the outer layer size of the roller buckle 33 is equal to twice the inner layer size, and the inner and outer layers of the roller buckle 33 are movably connected by a spring.

[0054] Specifically, when the stator module 14 as a whole follows the control base 12 to reciprocate and is in the winding process, the roller buckle 33 located at the bottom of the vertical sliding shaft 24 will gradually rise along the inclined surface of the auxiliary base 31, so that when the control base 12 is close to the coil assembly 13, the stator module 14 rises, and when the control base 12 is away from the coil assembly 13, the stator module 14 is lowered and restored to its original position. At this time, according to the position movement of the stator module 14, its own position change is synchronously adjusted. This winding method ensures that the copper wire can always remain taut during output, and effectively avoids tension fluctuations caused by changes in the copper wire's stretchable space. Relying on this constant tension control not only improves the compactness of the copper wire winding, making the spacing between each layer of copper wire more uniform, but also significantly enhances the tightness of the copper wire fitting on the stator coil skeleton, thereby improving the winding quality.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
