Description

Technical Field

[0001] The present invention relates to the technical field of winding components, and more particularly to an AC permanent magnet servo motor with wire connection protection. Background Art

[0002] The winding in an energy-saving AC permanent magnet servo motor is one of the key components. It is mainly responsible for converting electrical energy into mechanical energy, thereby driving the shaft. Secondly, AC permanent magnet servo motors have excellent dynamic performance and stability, and can provide more stable and rapid performance. This helps to improve the operational reliability of the equipment and reduce the production interruption caused by AC permanent magnet servo motor failures, resulting in energy loss caused by other equipment on the entire production line being in standby mode. Therefore, AC permanent magnet servo motors can also achieve energy conservation and cost reduction by reducing maintenance rates. Therefore, AC permanent magnet servo motors with lower failure rates have a more excellent energy conservation and cost reduction effect.

[0003] Among the existing published technical literature, Chinese Patent Publication No. CN213072252U discloses a lead-out structure for an AC permanent magnet servo motor. This technology utilizes a fan mounting plate secured to the rear end cover. The plate has a second wire hole positioned to align with the first. Fasteners are attached to the plate to secure the lead-out wires. During motor assembly, the lead-out wires first pass through the rear end cover, then through the fan mounting plate, and after being positioned by the fasteners, they ascend and enter the junction box. Sealant is applied to the wire hole in the fan mounting plate, improving the overall sealing of the motor. However, this technology still presents the following issues.

[0004] When the AC permanent magnet servo motor is in use, the wire connection point where the winding is connected will extend to the outside, thereby fixing the winding wire in a specified position. During the fixing process, the winding wire will be fixed by bending. If it is bent excessively, the winding wire will be easily damaged in the later stage. In addition, it is the connection position of the winding wire, which is inconvenient to replace and repair. It also requires other equipment in the entire production line to be shut down for maintenance, causing other equipment to lose energy in standby mode. Therefore, it is difficult to protect the wire connected to the winding according to the specified bending force and the specified bending position. It is difficult to avoid damage caused by excessive bending, the number of maintenance times is high, the maintenance cost increases, and the energy saving and cost reduction performance is poor. Therefore, an AC permanent magnet servo motor with wire connection protection is required. Summary of the Invention

[0016] 1. The present invention uses a constant force bending mechanism. The collar drives multiple connecting harnesses to bend and pull downward, and the collar begins to move and contact the inner wall of the positioning plate. At the same time, the collar drives the connecting block to pull, and the tension spring drives the linkage block to bend and stretch. The linkage block drives the sensing end of the tension sensor to stretch. When the bending tension value sensed by the tension sensor is the same as the bending tension value set by the controller, the outer wall of the collar is tied and fixed to the positioning plate with a strap.

[0017] 2. The present invention utilizes an angle switching mechanism, which requires applying a large rotational force to the rotating frame. Since the sleeve ring supports the support ring and the limit ring supports the rubber pressure ring, the rubber pressure ring can provide a large extrusion force on the rotating ring. The rotating ring drives the barcode to rotate. When the barcode rotates to the lowest bending angle, the rotating frame is loosened and the rotating ring is fixed under the action of the extrusion elastic force of the rubber pressure ring. In this way, the bending angle positions of multiple connecting harnesses are quickly determined, and they are bent and fixed at the specified angle, avoiding excessive bending of the connection between the winding end wire and the multiple connecting harnesses, and avoiding bending and damage to multiple connecting harnesses.

[0018] 3. The present invention adopts a bending positioning mechanism, a micro motor drives the driving gear to rotate, and the driven gear drives the linkage ring to rotate. The linkage ring and the driven gear both rotate on the outer wall of the groove ring, and the positioning plate causes the barcode recognition sensor to rotate. When the barcode recognition sensor recognizes the barcode value of the barcode, the micro motor is turned off by the controller, and then the bending positioning angle value is set on the controller. The controller starts the push block to push up, the rotating gear drives the linkage shaft to rotate counterclockwise, and the positioning plate drives the barcode recognition sensor to rotate counterclockwise. When the angle value sensed by the angle sensor is the same as the bending positioning angle value set on the controller, the positioning plate can be rotated to the specified bending positioning angle position, and can protect and fix multiple connecting harnesses and winding end wires according to the specified bending position to avoid damage caused by excessive bending of multiple connecting harnesses and winding end wires, and the winding end wire connection is better protected.

[0019] Based on the interaction of the above multiple functions, the barcode is first rotated to the lowest bending angle position. Secondly, the winding end wires and the wires connected to the multiple connecting wire harnesses can be protectively fixed according to the specified bending force. Finally, the multiple connecting wire harnesses and the winding end wires can be protectively fixed according to the specified bending force and the specified bending position. In summary, the winding end wires and the wires connected to the multiple connecting wire harnesses can be protectively fixed according to the specified bending force and the specified bending position, avoiding damage caused by excessive bending, greatly reducing maintenance costs, and achieving better energy and cost reduction.

Both the rack 37 and the push block 38 are slidably connected to the hinge block 29. A gap is provided between the drive gear 25 and the linkage ring 28, and the vertical cross-section of the linkage ring 28 is annular.

[0038] The working principle of the AC permanent magnet servo motor with wire connection protection of the present invention is as follows:

[0039] Step 1: When switching angles, first use bolts to fix the mounting bracket 15 to the mounting bracket. The mounting bracket 15 supports the housing 1 to increase the stability of the housing 1. At the same time, the hand rotates the rotating frame 19, which drives the rotating ring 20 to rotate. A large rotational force needs to be applied to the rotating frame 19. Since the collar 6 supports the support ring 16, the support ring 16 supports the limit ring 17, and the limit ring 17 supports the rubber pressure ring 18, the rubber pressure ring 18 can provide a large extrusion force on the rotating ring 20, so that the rotating ring 20 can be forced to rotate between the limit support ring 22 and the rubber pressure ring 18. At the same time, the rotating ring 20 drives the barcode 21 to rotate. When the barcode 21 rotates to the lowest bending angle, the rotating frame 19 is loosened, and the rotating ring 20 is fixed under the action of the squeezing elastic force of the rubber pressure ring 18. In this way, the bending angle position of the multiple connecting harnesses 5 is determined.

[0040] In step 2, during bending and positioning, the multiple connecting harnesses 5 are kept horizontally straightened, and at the same time, the multiple connecting harnesses 5 drive the collar 6 to be horizontally straightened. The controller 27 starts the micro-motor 26, and the micro-motor 26 drives the driving gear 25 to rotate. The driving gear 25 drives the driven gear 24 to engage and rotate. The driven gear 24 drives the linkage ring 28 to rotate. The linkage ring 28 and the driven gear 24 both rotate on the outer wall of the groove ring 23. At the same time, the linkage ring 28 drives the hinge block 29 to rotate. The hinge block 29 rotates the linkage shaft 30, and the linkage shaft 30 drives the collar block 33 to rotate. The collar block 33 drives the positioning plate 34 to rotate. The positioning plate 34 rotates the barcode recognition sensor 35. The barcode recognition sensor 35 rotates around the outside of the collar 6. When the barcode recognition sensor 35 recognizes the barcode value of the barcode 21, the micro-motor 26 is turned off by the controller 27. In this way, the positioning plate 34 can rotate to a position aligned with the barcode 21, so that the positioning plate 34 can move to the angle position where the multiple connecting harnesses 5 are bent and fixed.

[0041] By setting the bending positioning angle value on controller 27, controller 27 activates push block 38 to push upward, driving rack 37 upward. Rack 37 drives rotating gear 36 counterclockwise, which in turn drives linkage shaft 30 counterclockwise. Linkage shaft 30 rotates counterclockwise within hinge block 29. Linkage shaft 30 simultaneously drives sleeve block 33 counterclockwise, which in turn drives positioning plate 34 counterclockwise, which in turn drives barcode recognition sensor 35 counterclockwise. Linkage shaft 30 also rotates the sensing end of angle sensor 31. Hinge block 29 supports support block 32, which in turn supports angle sensor 31. Angle sensor 31 senses the angle of linkage shaft 30. When the angle value sensed by sensor 31 matches the bending positioning angle value set on controller 27, controller 27 deactivates push block 38, allowing positioning plate 34 to rotate to the specified bending positioning angle.

[0042] Step 3: When the fixed force is bent, the collar 6 is bent downward, and the collar 6 drives the multiple connecting harnesses 5 to bend and pull downward. The collar 6 begins to move toward the inner wall of the positioning plate 34 and contacts it. At the same time, the collar 6 drives the connecting block 7 to pull, and the connecting block 7 drives the tension spring 8 to stretch and bend. The tension spring 8 drives the linkage block 9 to bend and stretch, and the linkage block 9 drives the sensing end of the tension sensor 10 to stretch. The tension sensor 10 senses the bending tension. When the outer wall of the collar 6 contacts the positioning plate 34, the positioning plate 34 can position the collar 6 according to the specified angle, and the bending installation position of the multiple connecting harnesses 5 can be positioned.

[0043] When the bending tension value sensed by the tension sensor 10 is the same as the bending tension value set by the controller 27, it is checked through the display screen of the controller 27. Once the values ​​are the same, the outer wall of the ring 6 is tied and fixed to the positioning plate 34 with a strap, so that the multiple connecting wire harnesses 5 on the ring 6 can be fixedly installed according to the specified bending tension. At the same time, the multiple connecting wire harnesses 5 can also be positioned and fixedly installed according to the specified bending angle, avoiding excessive bending of the multiple connecting wire harnesses 5 and bending damage to the multiple connecting wire harnesses 5. The connection between the winding end wire 2 and the multiple connecting wire harnesses 5 can be protected from excessive bending. The connection between the multiple connecting wire harnesses 5 and the winding end wire 2 is not easy to bend and damage. The winding coil 4 does not need to be frequently disassembled and replaced, is more durable, not easy to be damaged, and the maintenance cost is greatly reduced, with better energy saving and cost reduction.

[0044] Step 4. When powered on and used, after the multiple connecting harnesses 5 are bent and fixed, they are docked in the power-on position through the terminals 11 on the multiple connecting harnesses 5. The power supply terminal 11 conducts electricity to the connecting harness 5, and the connecting harness 5 conducts electricity to the winding end wire 2. The winding end wire 2 conducts electricity to the winding connecting wire 3, and the winding coil 4 is conducted through the winding connecting wire 3. The winding coil 4 is supported by the AC iron core 12. The winding coil 4 can drive the permanent magnet rotor 13 to rotate, and the permanent magnet rotor 13 drives the rotating shaft 14 to rotate inside the casing 1, so that the AC permanent magnet drive operation can be performed.
