AI Technical Summary
In the existing technology, when winding the motor core, it is difficult to align the center of the die head with the center of the core, which leads to gaps at both ends during winding and easily damages the enameled wire.
A positioning compensation mechanism and a detection mechanism are adopted. The initial positioning is achieved by the positioning bracket abutting against the bottom end face of the lamination structure of the iron core. The displacement is detected by the contact between the detection sleeve and the top face. The thickness and center position of the lamination structure are calculated. The compensation drive component is used to adjust the center of the iron core to align with the winding die head to ensure that the enameled wire is uniform and compact.
It effectively eliminates winding gaps, improves winding effect, and ensures the magnetism of the motor and the quality of winding.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of motor winding equipment, and in particular to a core winding support device. Background Technology
[0002] The motor core is a crucial component of an electric motor, bearing the motor's magnetic field and mechanical forces, and having a vital impact on the motor's performance and efficiency. Motor cores typically employ a laminated structure, which is composed of multiple thin silicon steel sheets stacked together. Each silicon steel sheet undergoes special treatment to reduce iron losses and hysteresis losses, thereby improving the motor's efficiency.
[0003] Currently, for electric motors, stator core winding and rotor core winding are crucial steps that affect product quality. For stator and rotor cores with outward-facing slots, a flying fork winding machine is commonly used. Traditional winding machines include a winding section and a support section for supporting the core. The winding section includes a die, a flying fork for rotating the wire around the center of the die, and wire guides for guiding the wire onto the core. The position of the guides on the die is basically fixed. However, due to the different thicknesses of the coating layers on the laminated structures of each core, there are tolerances, making it difficult to align the center of the die with the center of each core. This can easily lead to gaps in the enameled wire at both ends of the core, with varying gap sizes. Furthermore, it can easily damage the enameled wire. Utility Model Content

[0011] In some embodiments, a clearance groove is provided on the side wall of the bushing portion, and the clearance groove extends from one end of the bushing portion in a direction perpendicular to the surface of the substrate to the other end of the bushing portion.
[0012] In some embodiments, the compensation drive assembly includes a lead screw extending in a direction perpendicular to the surface of the substrate, a nut seat connected to the lead screw, and a compensation power member for rotating the lead screw, with the compensation mounting bracket fixed to the nut seat.
[0013] In some embodiments, the shaft clamp is rotatably mounted on a compensation mounting bracket, which is provided with a rotary drive assembly capable of rotating the shaft clamp.
[0014] In some embodiments, the shaft clamp includes a clamping cylinder and a driving cylinder.

Based on the displacement of the detection sleeve, the distance between the top end surface of the lamination structure and the reference surface can be determined, thereby calculating the thickness and center position of the iron core lamination structure. Then, the control compensation drive component drives the compensation mounting bracket to move the shaft clamp and the iron core fixed on the shaft clamp, so that the center of the iron core is aligned with the center of the winding die head, thereby ensuring that the enameled wire is more uniform and compact at both ends of the iron core, which can basically eliminate gaps, improve the winding effect, and ensure the magnetism of the motor.

[0029] like Figures 1 to 6As shown, the iron core winding support device 100 provided in this embodiment includes a base plate 102, a positioning compensation mechanism 10, a support frame 20 disposed above the base plate 102, and a detection mechanism 30 mounted on the support frame 20. The positioning compensation mechanism 10 includes a compensation mounting frame 11 movably disposed below the base plate 102 in a direction perpendicular to the surface of the base plate 102, a compensation drive assembly 12 for driving the compensation mounting frame 11 to move in a direction perpendicular to the surface of the base plate 102, a shaft clamp 13 supported on the compensation mounting frame 11 and used to fix the iron core 200, and a positioning assembly 14. The positioning assembly 14 includes a positioning... The bracket 141 has a reference surface 141a for abutting against the bottom end face of the lamination structure 201 in the iron core 200. The reference surface 141a is located above the shaft clamp 13 and spaced at a predetermined distance from the shaft clamp 13. The detection mechanism 30 includes a detection sleeve 31 that is movably disposed on the support frame 20 in a direction perpendicular to the surface of the substrate 102 and for abutting against the top end face of the lamination structure 201 in the iron core 200, a sleeve drive member 32 for driving the detection sleeve 31 to move in a direction perpendicular to the surface of the substrate 102, and a displacement sensor 33 for detecting the displacement of the detection sleeve 31.
[0030] The aforementioned iron core winding support device 100 includes a positioning compensation mechanism 10 and a detection mechanism 30. The positioning compensation mechanism 10 includes a compensable mounting bracket 11, a compensation drive assembly 12, a shaft clamp 13, and a positioning assembly 14. The positioning assembly 14 includes a positioning bracket 141, which has a reference surface 141a for abutting against the bottom end face of the lamination structure 201 in the iron core 200. The detection mechanism 30 includes a detection sleeve 31 for abutting against the top end face of the lamination structure 201 in the iron core 200, a sleeve drive member 32 for driving the detection sleeve 31 to move in a direction perpendicular to the surface of the substrate 102, and a displacement sensor 33 for detecting the displacement of the detection sleeve 31. Thus, the reference surface 141a of the positioning bracket 141 abuts against the bottom end face of the lamination structure 201 in the iron core 200. The iron core 200 is initially positioned by the contact surface. After the detection sleeve 31 moves down and contacts the top surface of the lamination structure 201 of the iron core 200, the displacement sensor 33 detects and obtains the displacement of the detection sleeve 31. Based on the displacement of the detection sleeve 31, the distance between the top surface of the lamination structure 201 and the reference surface 141a can be determined, thereby calculating the thickness and center position of the lamination structure 201 of the iron core 200. Then, the control compensation drive assembly 12 drives the compensation mounting bracket 11 to move the shaft clamp 13 and the iron core 200 fixed on the shaft clamp 13, so that the center of the iron core 200 is aligned with the center of the winding die head, thereby ensuring that the enameled wire (not shown) is more uniform and compact at both ends of the iron core 200, which can basically eliminate gaps, improve the winding effect, and ensure the magnetism of the motor.
[0031] SeeFigures 1 to 6 The iron core winding support device 100 provided in this embodiment includes a frame 101 with a base plate 102. A winding device (not shown), a positioning compensation mechanism 10, a support frame 20, and a detection mechanism 30 are provided on the base plate 102. The positioning compensation mechanism 10 is used to fix the iron core 200 to be wound. The detection mechanism 30 is supported on the support frame 20. In this embodiment, the detection mechanism 30 is supported above the positioning compensation mechanism 10 by the support frame 20. The detection mechanism 30 can detect the thickness of the iron core 200. The positioning compensation mechanism 10 is mostly located below the base plate 102. The positioning compensation mechanism 10 can clamp the iron core 200 and drive the iron core 200 to move in a direction perpendicular to the surface of the base plate 102 to adjust the height position of the iron core 200 to adapt to the winding device. In this way, the overall structure is more compact and the volume is smaller.
[0032] See Figure 1 and Figure 2 The iron core winding support device 100 provided in this embodiment can be applied to the positioning compensation and winding of straight slot iron cores, and can also be applied to inclined slot iron cores. The iron core 200 includes a lamination structure 201, a mandrel 202 passing through the lamination structure 201, a commutator 203 mounted on the mandrel 202, and a hook 204 disposed on the outer periphery of the commutator 203.
[0033] See Figures 1 to 6The positioning compensation mechanism 10 provided in this embodiment includes a compensation mounting frame 11 movably disposed below the substrate 102 in a direction perpendicular to the surface of the substrate 102, a compensation drive assembly 12 for driving the compensation mounting frame 11 to move in a direction perpendicular to the surface of the substrate 102, a shaft clamp 13 supported on the compensation mounting frame 11 and used to fix the iron core 200, and a positioning assembly 14. The positioning assembly 14 includes a positioning bracket 141, which has a reference surface 141a for abutting against the bottom end face of the lamination structure 201 in the iron core 200. The reference surface 141a is located above the shaft clamp 13 and spaced at a predetermined distance from the shaft clamp 13. In this embodiment, The preset distance can be set according to the center position of the lamination structure 201 of the iron core 200 before compensation (i.e., initial timing), so that the center position is slightly lower than the center position of the winding device, but not limited to 0.5mm. The compensation mounting frame 11 is mounted on the frame 101 and located below the substrate 102. The compensation drive assembly 12 is mounted on the frame 101 and connected to the compensation mounting frame 11, and can drive the compensation mounting frame 11 to move up and down (i.e. move in a direction perpendicular to the surface of the substrate 102). The shaft clamp 13 and the positioning assembly 14 are respectively supported on the compensation mounting frame 11 and are driven by the compensation mounting frame 11 to move up and down together. It is worth mentioning that after the spindle 202 of the iron core 200 is inserted into the shaft clamp 13, it is held by the shaft clamp 13. Since the insertion part of the spindle 202 cannot be precisely controlled, it is difficult to measure the thickness of the lamination structure 201 of the iron core 200. However, by using the positioning component 14 mentioned above, the reference surface 141a on the positioning bracket 141 can abut against the bottom end surface of the lamination structure 201, thereby holding the lamination structure 201 on a preset plane. Then, the thickness dimension of the lamination structure 201 can be accurately obtained by the detection mechanism 30. Then, the compensation drive component 12 drives the compensation mounting bracket 11 to move the shaft clamp 13 and the iron core 200 together to compensate for the height position of the iron core 200, so that the center of the lamination structure 201 is aligned with the center of the winding device. In this way, the flying fork component of the winding device rotates and winds the wire around the wire passing through the center, which makes the winding of the iron core 200 more uniform at both ends and improves the winding effect.
[0034] See Figures 1 to 6 In this embodiment, the compensation drive assembly 12 includes a lead screw 121 extending in a direction perpendicular to the surface of the substrate 102, a nut seat 122 connected to the lead screw 121, and a compensation power member 123 that rotates the lead screw 121. The compensation power member 123 is, but is not limited to, a motor. The compensation mounting bracket 11 is fixed on the nut seat 122. In this way, the movement accuracy of the compensation mounting bracket 11 is higher and the compensation distance is more accurate.
[0035] See Figures 1 to 6The positioning bracket 141 provided in this embodiment includes a bushing portion 142 sleeved outside the shaft clamp 13 and a connecting portion 143 connected to the bushing portion 142. The reference surface 141a is located on the top surface of the bushing portion 142. The positioning assembly 14 also includes a bracket power member 144 for moving the positioning bracket 141 in a direction perpendicular to the surface of the substrate 102. The bracket power member 144 is supported on the compensation mounting bracket 11 and connected to the connecting portion 143. In this embodiment, the shaft clamp 13 has a generally circular cross-section. The positioning bracket 141 includes a bushing portion 142 and a connecting portion 143. The reference surface 141a is located on the top surface of the bushing portion 142. The shape of the bushing portion 142 is adapted to the shaft clamp 13, and the inner diameter of the bushing portion 142 is larger than the diameter of the shaft clamp 13. The bracket power member 144 is supported on the compensation mounting bracket 11. The connecting portion 143 is connected to the bracket power member 144. The bracket power member 144 is, but is not limited to, a cylinder. It can be understood that before the iron core 200 is placed, the reference surface 141a is located above the shaft clamp 13, so that the shaft clamp 13 is spaced apart from the stacked structure 201, avoiding contact between the shaft clamp 13 and the stacked structure 201. After the positioning compensation mechanism 10 compensates and adjusts the height position of the iron core 200, the bracket power member 144 drives the positioning bracket 141 to move downward (lower in the figure), so that the positioning bracket 141 separates from the stacked structure 201.
[0036] In other embodiments, the positioning bracket 141 may also be moved horizontally away from the iron core 200.
[0037] See Figures 1 to 6 The bushing portion 142 provided in this embodiment has a clearance slot 1421 on its side wall. The clearance slot 1421 extends from one end of the bushing portion 142 in a direction perpendicular to the surface of the substrate 102 to the other end of the bushing portion 142. The clearance slot 1421 is arranged facing the winding device. In this way, interference with the enameled wire can be avoided during winding to prevent damage to the equipment.
[0038] See Figures 1 to 6 The shaft clamp 13 provided in this embodiment is rotatably mounted on the compensation mounting frame 11. The compensation mounting frame 11 is provided with a rotary drive assembly 15 that enables the shaft clamp 13 to rotate. In this embodiment, the rotary drive assembly 15 is mounted on the compensation mounting frame 11 and supported by the compensation mounting frame 11. The rotary drive assembly 15 can make the shaft clamp 13 rotate around the axis of the shaft clamp 13. In this way, when winding, the iron core 200 can be driven to rotate by the rotary drive assembly 15, so as to facilitate winding of each tooth on the iron core 200.
[0039] See Figures 1 to 6The shaft clamp 13 provided in this embodiment includes a clamping cylinder 131 and a driving cylinder 132. The clamping cylinder 131 has a flared end 1311 with a tapered outer wall for the mandrel 202 of the iron core 200 to slide in and out. The clamping cylinder 131 includes a plurality of elastic claws 1312 located at the flared end 1311. The plurality of elastic claws 1312 are arranged at intervals along the circumference of the clamping cylinder 131. The driving cylinder 132 is sleeved outside the clamping cylinder 131 and can clamp and release the mandrel 202 with the elastic claws 1312. The compensation mounting bracket 11 is provided with a shaft clamping power component 1321 that can drive the driving cylinder 132 to move relative to the clamping cylinder 131. In this embodiment, the shaft clamping power component 1321 is, but is not limited to, a cylinder. The driving cylinder 132 is rotatably but immovably connected to the cylinder. On the output shaft of the cylinder, the clamp 131 is rotatably mounted on the compensation mounting bracket 11 and connected to the compensation drive assembly 12. The clamp 131 and the drive cylinder 132 are movably but not rotatably connected by a key. It can be understood that the clamping shaft power member 1321 drives the drive cylinder 132 to move upward (above in the figure) in a direction perpendicular to the surface of the substrate 102, so that the multiple elastic claws 1312 of the flared end 1311 of the clamp 131 tighten to clamp the mandrel 202 of the iron core 200. The clamping shaft power member 1321 drives the drive cylinder 132 to move downward (below in the figure) in a direction perpendicular to the surface of the substrate 102, so that the multiple elastic claws 1312 of the flared end 1311 of the clamp 131 release the mandrel 202 of the iron core 200.
[0040] See Figure 1 The detection mechanism 30 provided in this embodiment includes a detection sleeve 31 (in a direction perpendicular to the surface of the substrate 102) that is movably disposed on the support frame 20 in a direction perpendicular to the surface of the substrate 102 and is used to abut against the top surface of the lamination structure 201 in the iron core 200; a sleeve drive member 32 for driving the detection sleeve 31 to move in a direction perpendicular to the surface of the substrate 102; and a displacement sensor 33 for detecting the displacement of the detection sleeve 31. In this embodiment, the inner diameter of the detection sleeve 31 is larger than that of the commutator 203, and the outer diameter is smaller than that of the lamination structure 201. It extends in a direction perpendicular to the surface of the substrate 102 and is vertically mounted on the support frame 20. The sleeve drive 32 is, but is not limited to, a cylinder. It is fixed on the support frame 20 and connected to the detection sleeve 31. Under the drive of the sleeve drive 32, the detection sleeve 31 can move up and down relative to the support frame 20. Thus, after the iron core 200 is placed on the positioning bracket 141, the detection sleeve 31 moves down (lower in the figure) and contacts the top surface of the lamination structure 201 of the iron core 200. At the same time, the displacement sensor 33 measures the travel of the detection sleeve 31 and transmits it to the processor (not shown) to calculate the thickness and center height of the lamination structure 201. The processor then controls the positioning compensation mechanism 10 to perform height compensation. The processor is any existing processor in the prior art that can achieve the above functions.
[0041] See Figure 2 and Figures 1 to 6 In this embodiment, a detection plate 34 is connected to the detection sleeve 31, and a displacement sensor 33 is mounted on the support frame 20 and located below the detection plate 34. Thus, when the detection sleeve 31 moves the detection plate 34 downwards, the detection plate 34 pushes the probe of the displacement sensor 33 downwards. It is understood that before the iron core 200 is placed, the positioning bracket 141 moves to a preset position, causing the reference surface 141a on the positioning bracket 141 to move to a preset plane. After the iron core 200 is placed on the reference surface 141a, the bottom end face of the lamination structure 201 of the iron core 200 abuts against the reference surface 141a, and simultaneously, the shaft clamp 13 clamps the mandrel 202 of the iron core 200. After the detection sleeve 31 moves downwards and contacts the top end face of the lamination structure 201 of the iron core 200, the displacement sensor... The displacement of the detection sleeve 31 can be obtained by detecting the displacement of the detection sleeve 31. The distance between the top surface of the lamination structure 201 and the reference surface 141a can be obtained from the displacement of the detection sleeve 31. Thus, the thickness of the lamination structure 201 of the iron core 200 and the center position of the lamination structure 201 can be calculated. The control compensation drive assembly 12 drives the compensation mounting bracket 11 to move the shaft clamp 13 and the iron core 200 fixed on the shaft clamp 13, so that the center of the iron core 200 is aligned with the center of the winding die (not shown).
[0042] See Figures 1 to 6In this embodiment, the support frame 20 is provided with a docking shaft 35 for abutting against the top surface of the commutator 203 in the iron core 200. The docking shaft 35 has a receiving groove 351 for inserting the mandrel 202 of the iron core 200. The detection sleeve 31 is sleeved outside the docking shaft 35. In this embodiment, the docking shaft 35 extends in a direction perpendicular to the surface of the substrate 102. The docking shaft 35 has a receiving groove 351 for inserting the upper end (upper end in the figure) of the mandrel 202 of the iron core 200. The detection sleeve 31 is sleeved outside the docking shaft 35, and the upper end (upper end in the figure) of the docking shaft 35 protrudes from the upper end of the detection sleeve 31. The docking shaft 35 is fixed on the support frame 20. The inner diameter of the docking shaft 35 matches the diameter of the mandrel 202. The diameter is smaller than that of the commutator 203. A support frame 40 is provided on the base plate 102. The support frame 20 is movably mounted on the support frame 40 in a direction perpendicular to the surface of the base plate 102. The support frame 40 is provided with a support lifting power member 41 for driving the support frame 20 to move in a direction perpendicular to the surface of the base plate 102. The support lifting power member 41 is, but is not limited to, a cylinder. Under the drive of the support lifting power member 41, the support frame 20 moves up and down and drives the docking shaft 35 and the detection sleeve 31 mounted on it to move up and down together. It can be understood that during winding, the docking shaft 35 moves down and abuts against the commutator 203. By clamping the iron core 200 with the shaft clamp 13 and the docking shaft 35, the iron core 200 can be fixed more firmly and avoid deviation during winding.
[0043] See Figures 3 to 6 In this embodiment, the support frame 20 is provided with a wire pressing cylinder 36 for abutting against the hook 204 of the iron core 200. The wire pressing cylinder 36 is disposed between the docking shaft 35 and the detection sleeve 31. The support frame 20 is provided with a wire pressing power member 37 for driving the wire pressing cylinder 36 to move in a direction perpendicular to the surface of the substrate 102. In this embodiment, the wire pressing cylinder 36 extends in a direction perpendicular to the surface of the substrate 102. The wire pressing cylinder 36 is installed between the docking shaft 35 and the detection sleeve 31 and is connected to the wire pressing power member 37. Its inner diameter is larger than the diameter of the commutator 203. The wire pressing power member 37 is, but is not limited to, a cylinder. Under the drive of the wire pressing power member 37, it can move relative to the detection sleeve 31 and the docking shaft 35 to press the wire end (not shown) onto the hook 204 on the outer periphery of the commutator 203 to fix the wire end.
[0044] See Figures 1 to 6 In this embodiment, a retaining seat 38 is provided at the end of the pressing cylinder 36. The retaining seat 38 is fixedly installed on the support frame 20. The retaining seat 38 is connected to the output shaft of the pressing power component 37. A bearing is provided between the retaining seat 38 and the pressing cylinder 36 to ensure that the pressing cylinder 36 can rotate together with the iron core 200.
[0045] The following is combined The compensation process of the iron core winding support device 100 provided in this embodiment will be described in detail:
[0046] The iron core 200 to be wound is placed on the clamp 13 of the positioning compensation mechanism 10. The lamination structure 201 of the iron core 200 abuts against the reference surface 141a of the positioning bracket 141 to position the bottom end face of the lamination structure 201. Then, the mandrel 202 of the iron core 200 is clamped by the clamp 13. After the support frame 20 moves down to the preset position under the drive of the support lifting power component 41, the sleeve drive component 32 of the detection mechanism 30 drives the detection sleeve 31 to move downward. After the detection sleeve 31 abuts against the fixed end face of the lamination structure 201, the movement stroke of the detection sleeve 31 can be measured by the displacement sensor 33, thereby obtaining the thickness dimension of the lamination structure 201 of the iron core 200. The sleeve drive component 32 drives the detection sleeve 31 to move upward to reset and separate it from the lamination structure 201. Then, the compensation drive component 12 drives the compensation. The mounting bracket 11 compensates for the height, aligning the center of the lamination structure 201 of the iron core 200 mounted on the shaft clamp 13 with the center of the winding die. Then, the positioning bracket 141 is moved downward by the support power component 144 to separate from the lamination structure 201. The bearing lifting power component 41 drives the bearing bracket 20 and the docking shaft 35 to move downward together, so that the bottom end of the docking shaft 35 abuts against the top surface of the commutator 203 of the iron core 200, thereby holding the upper part of the core shaft 202 of the iron core 200. During winding, after the wire end is hung on the hook 204 on the outside of the commutator 203, the wire pressing power component 37 drives the wire pressing cylinder 36 to move downward to press the wire end. At the same time, the detection sleeve 31 moves downward under the drive of the sleeve driving component 32 and covers the commutator 203 inside the detection sleeve 31, thereby protecting the commutator 203.

Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
