Description

Technical Field

[0001] The invention relates to the technical field of motor stator magnetization, in particular to an automatic motor stator magnetization integrated machine. Background Art

[0002] Permanent magnet motors are primarily categorized by the location of their permanent magnets: rotor permanent magnet and stator permanent magnet. In stator permanent magnet motors, the permanent magnets are embedded or mounted in specific locations within the stator core. This structure, which places the permanent magnets on a stationary stator, offers potential advantages over rotor permanent magnet motors, including a simpler and more robust rotor structure, relatively better heat dissipation, and a more easily controlled permanent magnet assembly process. These advantages make stator permanent magnet motors particularly suitable for high-speed applications.

[0003] Permanent magnets are the core excitation components of permanent magnet motors. To ensure they provide the required strong magnetic field in the motor's air gap, they must be magnetized. The magnetization process utilizes a strong external pulsed magnetic field (typically generated by a high, instantaneous current flowing through a magnetizing coil) to overcome the coercive force of the permanent magnet material, forcing its internal magnetic domains to align in a predetermined direction (the magnetization direction), thereby achieving saturation magnetization.

[0004] In the process of magnetizing the motor stator, the existing magnetizing machine generally uses a conveying device to transport a single stator to be magnetized to a designated workstation, and then uses a mechanical gripper to grab the single stator and place it in the magnetizing cylinder for magnetization operation. After the magnetization is completed, the mechanical gripper removes the stator from the magnetizing cylinder and places it on the subsequent conveyor line for subsequent processes.

[0005] However, the existing magnetizing machines do not have the ability to conduct timely online magnetic inspection of the stator magnetic energy after magnetization. Regardless of whether the magnetism of the stator meets the production standards, it is uniformly sent to the subsequent links. Additional testing equipment is needed to test the stator after magnetization. Otherwise, the quality of subsequent products cannot be guaranteed.

[0006] Moreover, since the stators can only be placed in, taken out and magnetized one by one, the utilization rate of the entire production line is limited. For some smaller motor stators, after being diverted in the feed rack, they are lower than the height of the feed rack and thus stay in the branch end of the feed rack. The mechanical gripper cannot reach into the feed rack for clamping operation, which affects the removal operation of the magnetized stator.

[0007] On this basis, the present invention provides an automatic motor stator magnetizing integrated machine to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0046] The above and other technical contents, features and effects of the present invention are described below with reference to the attached Figures 1 to 19 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the accompanying drawings.

[0047] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0048] The present invention is an automatic motor stator magnetizing integrated machine. For the existing magnetized stators, it is impossible to perform magnetic inspection operations in a timely manner, so that qualified and unqualified magnetized stators are mixed together, and a separate detection device needs to be set up to perform the detection operation.

[0049] The existing magnetizing machine can only transport and magnetize a single stator to be magnetized, and smaller stators cannot be grasped by a mechanical gripper.

[0050] As an embodiment, the present invention includes an automatic motor stator magnetizing integrated machine, such as Figure 1 and Figure 3As shown, it includes a box body 1, a bracket 3 and a placement rack 5. The top of the box body 1 is fixedly connected to a support plate 2. The top of the support plate 2 is fixedly connected to two magnetizing cylinders 7. The magnetizing cylinders 7 are connected to a power supply and a controller. A magnetizing cavity 8 is opened on the two magnetizing cylinders 7. The two magnetizing cavities 8 are respectively located at the center of the two magnetizing cylinders 7. A magnetizing coil is arranged in the magnetizing cylinder 7. By supplying power to the coil, according to Ampere's law, when current passes through the wire, a magnetic field will be generated around it, and therefore a magnetic field will be formed between the coils, forcing the tiny magnetic domains inside the stator subsequently placed in the magnetizing cavity 8 to deflect and arrange, thereby completing the magnetization operation. Four movable clamps 31 are arranged on the top of the box body 1, and each two clamps 31 form a group. The distance between the two clamps 31 in each group is the same as the distance between the centers of the two magnetizing cylinders 7. The "Y"-shaped feed rack 17 is fixed to the support plate 2 through the support seat 16.

[0051] like Figure 3 、 Figure 4 and Figure 5 As shown, its feed end extends to the bracket 3, and the two branch ends are respectively aligned with the two magnetizing cylinders 7. The distance between the branch ends is consistent with the distance between the magnetizing cylinders 7, and the three are flush in height. The feed end on the feed rack 17 is higher than the two branch ends, and is inclined from the high feed end to the low branch end, so that the stator entering the feed rack 17 can be smoothly diverted on the feed rack 17 and then enter the two branch ends, and then be used in conjunction with the two magnetizing cylinders 7. Two lifting and lowering support rods 47 are provided in the box body 1. The distance between the two support rods 47 is the same as the distance between the two magnetizing cylinders 7. Baffles 48 are fixedly connected to the two support rods 47, and limit plates 49 are slidably connected to the two support rods 47. The two limit plates 49 are respectively located above the two baffles 48. First tension springs 50 are provided between the two baffles 48 and the two limit plates 49, and the two first tension springs 50 are respectively sleeved on the two support rods 47.

[0052] like Figures 4 to 7As shown, the diameters of the two limit plates 49 are larger than the diameters of the corresponding baffles 48, which facilitates the subsequent pushing of the limit plates 49 to make the stator sleeved on the support rod 47 fall off, and both support rods 47 are provided with blocks which are not pointed out in the figure, to limit the limit plates 49 to prevent the limit plates 49 from moving downward too much due to the pulling of the first tension spring 50, thereby affecting the loading of the stator. The support rod 47 and the baffles 48 and limit plates 49 thereon can move freely in the magnetizing cavity 8. A servo motor 40 is fixedly connected to one side of the inner wall of the box body 1. The servo motor 40 is connected to a power supply, a reducer and a controller. The output end of the servo motor 40 is fixedly connected to the rotating shaft 41, and the first rotating rod 42 is installed on the rotating shaft 41. The first rotating rod 42 is provided with an elastic control contact 57 on the side close to the servo motor 40 to ensure contact control with the subsequent first contact 58, second contact 59, third contact 60 and fourth contact 61. The first contact 58, second contact 59, third contact 60 and fourth contact 61 are provided on one side of the inner wall of the first box body 1 in an arc shape with the rotating shaft 41 as the center. The control contact 57 can respectively contact and cooperate with the first contact 58, second contact 59, third contact 60 and fourth contact 61.

[0053] like Figure 3 、 Figure 8 、 Figure 10 and Figure 11 As shown, two circular penetration slots 32 are provided on the support plate 2, and the two magnetizing cavities 8 on the magnetizing cylinder 7 are in a state of vertical penetration. The spacing between the two penetration slots 32 is the same as the spacing between the two magnetizing cylinders 7. The two penetration slots 32 are respectively located below the two magnetizing cavities 8 and are connected to the two magnetizing cavities 8. A detection slot 33 is provided on the top of the box body 1, and a fixing frame 34 is fixedly connected to the detection slot 33. Two detection coils 35 are fixedly connected to the fixing frame 34. The detection coil 35 is connected to the power supply and the controller. The detection coil 35 includes structures such as an induction coil and a signal processor. It is a prior art and therefore is not described in detail. The two detection coils 35 are respectively located below the two penetration slots 32 and correspond to the two penetration slots 32.

[0054] like Figure 12 、 Figure 16 and Figure 17 As shown, one side of the inner wall of the box body 1 is fixedly connected to a fixed frame 37 through a connecting plate 36, and a bidirectional electric push rod 38 is fixedly connected to the fixed frame 37. The bidirectional electric push rod 38 is connected to the power supply and the controller. The bidirectional electric push rod 38 is located between the two support rods 47. The two output ends of the bidirectional electric push rod 38 are fixedly connected to L-shaped pushing blocks 39. The two pushing blocks 39 are respectively located below the two limit plates 49 and are in contact with the two limit plates 49.

[0055] In this embodiment, the "Y"-shaped feed rack 17 is tilted to slide the motor stator placed at the feed end of the feed rack 17 onto the feed rack 17, and then diverted to the two branch ends of the feed rack 17, so that a set of clamps 31 are used to clamp the stator and transfer it to the top of the magnetizing cylinder 7. Since the distance between the two branch ends of the feed rack 17 is the same as the distance between the two magnetizing cylinders 7, the stator can be directly placed on the limit plate 49 on the support rod 47, and then enter the magnetizing cylinder 7 for magnetization operation. The setting makes the feeding and magnetization synchronous, reduces the processing time of each stator, and thus speeds up the work efficiency. When the servo motor 40 is working, the first rotating rod 42 is driven to rotate by the rotating shaft 41 at the output end, thereby driving the control contact 57 on one side to move, and the servo motor 40 is controlled to stop when it contacts the first contact 58, the second contact 59, the third contact 60 and the fourth contact 61 respectively. When it contacts the first contact 58, the support rod 47 is pushed up to the highest position. At this time, the limit plate 49 on the support rod 47 is in the magnetization position. Above the cylinder 7, the clamped stator is placed on the support rod 47 with the help of the clamp 31, and is supported and limited by the limit plate 49. After the corresponding sensor on the support rod 47 detects that the stator is placed (or the servo motor 40 is set to stay for 3-5 seconds), the servo motor 40 is controlled to start again. When it contacts the second contact 59, the servo motor 40 stops, and the limit plate 49 is driven to descend through the support rod 47, driving the placed stator into the magnetizing cavity 8. The magnetizing coil in the magnetizing cylinder 7 is energized to work and the placed stator is magnetized. After the magnetization is completed, a signal is sent to the controller to start the servo motor 40 again. The limit plate 49 drops again. When it contacts the third contact 60, the limit plate 49 drives the stator from the magnetization cavity 8 to the detection coil 35 to perform a magnetic detection operation on the stator. The detection coil 35 is used to detect whether the stator is magnetic. When it meets the standard, the detection coil 35 sends a signal to the controller to control the servo motor 40 to reverse, driving the first rotating rod 42 to rotate in the opposite direction until the control contact 57 contacts the first contact 58 again, and the servo motor 40 stops working.

[0056] It should be noted that, after the stator is tested to be qualified, the servo motor 40 will not be controlled to stop when it reverses and passes the second contact 59 .

[0057] At this time, the magnetized and qualified stator is moved again to the top of the magnetization cylinder 7 to facilitate subsequent clamping.

[0058] When one of the stators fails the inspection, the stator continues to send a signal to control the servo motor 40 to start when it receives the signal of stator failure through the detection coil 35, and at the same time sends a signal to the bidirectional electric push rod 38. Through the extension of the bidirectional electric push rod 38, the corresponding push block 39 is controlled to move horizontally, and the push block 39 moves to the bottom of the unqualified stator. In the process of the support rod 47 continuing to descend, the push block 39 approaches the support rod 47, and the baffle 48 contacts the bottom of the limit plate 49 after passing, pushing the limit plate 49 to slide on the support rod 47, pushing the stator on the top of the limit plate 49, so that the stator slides and rises on the support rod 47 until it detaches.

[0059] When the stators on the two limit plates 49 are unqualified at the same time, the bidirectional electric push rod 38 pushes the two push blocks 39 to move synchronously to the bottom of the two limit plates 49, so that the support rod 47 can push the two limit plates 49 synchronously during the descent process. Through the synchronous push of the two limit plates 49, the top stator is separated from the support rod 47, so that the stator that fails the magnetic inspection can be separated from the qualified stator, reducing the subsequent process of separate magnetic inspection.

[0060] When the servo motor 40 rotates and contacts the fourth contact 61, the stator falls completely, the servo motor 40 stops and starts in the reverse direction to drive the support rod 47 back to the first contact 58, and at the same time, the bidirectional electric push rod 38 is reset.

[0061] It should be noted that, after the stator detection is set to be unqualified, the servo motor 40 will not be controlled to stop when it reverses from the fourth contact 61 to the first contact 58 and passes through the third contact 60 and the second contact 59.

[0062] As an example, Figures 10 to 14 As shown, one side of the detection slot 33 is slidably connected to a push plate 66, and the side of the push plate 66 close to the detection coil 35 is fixedly connected to a mounting plate 67, and two detection heads 68 connected to the two detection coils 35 are fixed on the mounting plate 67. The detection heads 68 on the two detection coils 35 are all fixedly connected to one side of the mounting plate 67, and the two detection heads 68 are respectively slidably penetrated through one side of the detection coil 35. Two second tension springs 69 are arranged between the mounting plate 67 and the detection slot 33, and the bottom of the push plate 66 is fixedly connected to a first rack 73, and one side of the detection slot 33 is rotatably connected to a movable shaft 70, and a driving gear 72 is fixedly connected to the movable shaft 70, and the driving gear 72 is meshed with the first rack 73. The driving gear 72 is connected to a one-way gear 71 via the coaxial movable shaft 70, and a second rack 74 that can slide up and down is meshed on the side of the one-way gear 71.

[0063] It should be noted that if Figure 17As shown, the one-way gear 71 includes an inner wheel fixedly mounted on the movable shaft 70 , on which symmetrically arranged pawls rotate, and a ratchet is mounted on the outer side of the pawl, and the outer circumference of the ratchet is formed by external teeth that mesh with the first rack 73 .

[0064] It should also be noted that the detection coil 35 for stator magnetic detection can be non-contact detection or contact detection. Both non-contact detection and contact detection are existing technologies, which can detect whether the magnetization is qualified. Non-contact detection is more convenient and flexible, and contact detection results are more accurate and reliable.

[0065] Now, an embodiment of contact detection is provided. In this embodiment, Figures 11 to 17 As shown, in the process of the stator descending from the magnetizing cavity 8 to the detection coil 35, the second rack 74 moves downward to engage the one-way gear 71. At this time, the one-way gear 71 rotates counterclockwise. When the one-way gear 71 rotates counterclockwise, it can drive the movable shaft 70 to rotate, and at the same time drive the driving gear 72 to rotate. The driving gear 72 drives the first rack 73 to move, thereby driving the detection head 68 to slide into the detection coil 35 and contact with the stator moving in the detection coil 35 to realize contact detection. The contact detection at this time is not a compression detection.

[0066] If the test fails, the second rack 74 continues to move downward. At this time, the second rack 74 is disengaged from the one-way gear 71. After the second rack 74 disengages from the one-way gear 71, the detection head 68 is reset under the action of the second tension spring 69, and the second rack 74 engages with the one-way gear 71 during the reverse upward movement, causing the one-way gear 71 to rotate clockwise. At this time, the one-way gear 71 is idling and does not drive the movable shaft 70 to rotate. The detection head 68 does not move, so that the stator that has passed the test can pass smoothly.

[0067] Similarly, if the test is qualified, the second rack 74 moves upward in the opposite direction. Since the contact test is not a compression test, the stator moves upward from the detection coil 35. When the second rack 74 disengages from the one-way gear 71, the detection head 68 is reset under the action of the second tension spring 69.

[0068] As an example, Figure 8 、 Figure 9 and Figure 15 As shown, a slide groove 63 is provided at the bottom of the two branch ends of the feed rack 17, and the two slide grooves 63 pass through the support plate 2 and are connected to the box body 1. Push rods 64 are slidably connected in the two slide grooves 63, and the top ends of the two push rods 64 are respectively flush with the tops of the two slide grooves 63. The bottom ends of the two push rods 64 are connected to a fixed plate 76, and the two fixed plates 76 are both located in the box body 1. A third spring 65 is sleeved on the two push rods 64, and the two third springs 65 are both located between the fixed plate 76 and the top of the inner wall of the box body 1.

[0069] like Figure 12 、 Figure 4 and Figure 14 As shown, two slide bars 45 are fixedly connected to the top of the inner wall of the box body 1, and a sliding sleeve 46 is slidably connected to the two slide bars 45. The opposite sides of the two sliding sleeves 46 are fixedly connected to the frame 44. A through slot is provided on the frame 44 so that the two-way electric push rod 38 and the push block 39 fixed on the fixed frame 37 can pass through the through slot. The two support rods 47 are fixedly connected to the bottom of the inner wall of the frame 44. A drop opening 51 is provided at the bottom of the frame 44. The drop opening 51 is located on one side of the through slot. The inner wall of the box body 1 is fixed on one side. It is connected to a storage frame 52, which is located below the drop port 51. The other end of the first rotating rod 42 is rotatably connected to the second rotating rod 43. The other end of the second rotating rod 43 is rotatably connected to the bottom of the frame 44. The top of the frame 44 is connected to a second rack 74, which can engage with the one-way gear 71. The second rack 74 and the first rack 73 are vertically staggered. Two pushing frames 75 are connected to one side of the frame 44, and the two pushing frames 75 are respectively in contact with two fixed plates 76.

[0070] like Figure 6 and Figure 7 As shown, a fixed sleeve 53 is fixedly connected to the first rotating rod 42, and a side of the fixed sleeve 53 close to the control contact 57 is fixedly connected to the limit rod 54, and the other end of the limit rod 54 is movably sleeved with the limit sleeve 55. A second spring 56 is provided between one end of the limit rod 54 and the limit sleeve 55, and the second spring 56 is located in the limit sleeve 55. A control contact 57 is fixedly connected to the inner side of the limit sleeve 55, and the control contact 57 is in contact with the first contact 58, the second contact 59, the third contact 60 and the fourth contact 61. The first contact 58, the second contact 59, the third contact 60 and the fourth contact 61 are connected to the same contact sensor 62 through wires and are connected to the power supply and the controller.

[0071] In this embodiment, the pushing frame 75 is driven to rise during the rising process of the frame 44. During the continuous rising process of the pushing frame 75, it first contacts the bottom of the two fixed plates 76, thereby pushing the two fixed plates 76 to rise. During the rising process of the two fixed plates 76, the two push rods 64 are pushed to move in the two slide grooves 63, and the stators in the two branch ends of the feed frame 17 are pushed to rise. When the control contact 57 contacts the first contact 58, that is, when the support rod 47 reaches the highest point, the push rod 64 drives the two stators to move to the highest point and stop, so that some smaller stators can be When the locking cam 75 is in the unlocking state, the locking cam 75 is in the unlocking state, and the locking cam 75 is in the unlocking state, so that the locking cam 75 is locked and the master latch 73 is locked.

[0072] The stator that falls into the frame 44 falls into the storage frame 52 through the drop port 51 for storage. When the pushing block 39 pushes the limit plate 49 to move upward, the first tension spring 50 between the limit plate 49 and the baffle 48 will be stretched, causing the first tension spring 50 to generate a reverse force. After the stator that fails the magnetic inspection is pushed out, the frame 44 drives the support rod 47 to rise, and the limit plate 49 is reset by the pulling of the first tension spring 50. Through the control contact 57, when the servo motor 40 drives the first rotating rod 42 to rotate, the control contact 57 is driven to move along the trajectory of the first contact 58, the second contact 59, the third contact 60 and the fourth contact 61, thereby cooperating with the height positioning operation of the support rod 47 in the frame 44.

[0073] As an example, Figure 2 and Figure 18As shown, a distribution tray 4 is provided on the top of the bracket 3, and the four corner areas of the top of the bracket 3 are fixedly connected with inner tubes 9, and the four corner areas of the bottom of the distribution tray 4 are fixedly connected with outer tubes 10. The diameters of the four inner tubes 9 are smaller than the diameters of the four outer tubes 10. The four inner tubes 9 and the outer tubes 10 are all located between the bracket 3 and the distribution tray 4. The upper ends of the four inner tubes 9 are respectively slidably connected to the four outer tubes 10. The four outer tubes 10 are all sleeved with first springs 11. The four first springs 11 are respectively sleeved on the four inner tubes 9, and their bottom ends abut or are fixed on the inner tube 9. The bottom of the distribution tray 4 is fixedly connected with a vibration motor 12, which is connected to a power supply and a controller. The bottom of the inner wall of the distribution tray 4 is fixedly connected with a feeder. The ramp 13, through the feeding ramp 13, causes the vibration motor 12 to drive the distribution tray 4 to shake, and the stator moves along the inner wall of the distribution tray 4 until it enters between the two baffle plates 14 and is discharged from the discharge port 15 through the two baffle plates 14. The distribution tray 4 is provided with a discharge port 15 on the side close to the box body 1, and baffle plates 14 are fixedly connected on both sides of the discharge port 15. The two baffle plates 14 are fixedly connected to the bottom of the inner wall of the distribution tray 4, and the feeding end of the feeding rack 17 is located in the discharge port 15. The feeding end of the feeding rack 17 has an opening, which is opposite to and receives the stator falling from the discharge port 15 on the distribution tray 4, so that the stator discharged from the distribution tray 4 can smoothly enter the feeding rack 17 and cooperate with the distribution tray 4.

[0074] In this embodiment, the vibrating motor 12 drives the distribution tray 4 to vibrate, driving the four outer tubes 10 to slide on the four inner tubes 9. By buffering the first spring 11, the stator placed on the distribution tray 4 slides along the feeding slope 13 and sticks to the inner wall of the distribution tray 4, and finally moves to the discharge port 15, and slides into the feed rack 17 from the discharge port 15.

[0075] As an example, Figure 2 and Figure 3 As shown, the top of the support plate 2 is fixedly connected to a conveyor belt 19 through a mounting seat 18. The conveyor belt 19 includes a drive motor, a transmission roller, an idler roller, a tensioning device and a frame. It is a prior art and is not described in detail. The conveyor belt 19 is located on the side of the two magnetizing cylinders 7 away from the feed rack 17. The tops of both sides of the conveyor belt 19 are fixedly connected to guide plates 20. The guide plates 20 are located above the conveyor belt 19 to limit the stator during transportation. A storage box 6 is placed on the top of the placement rack 5. A blanking plate 21 is fixedly connected to the bottom of the side of the conveyor belt 19 close to the storage box 6. The bottom of the blanking plate 21 is located above the storage box 6. The blanking plate 21 is tilted from the position of the conveyor belt 19 toward the direction of the storage box 6, so that the transported stator can smoothly fall into the storage box 6 for storage.

[0076] In this embodiment, the conveyor belt 19 continuously operates to convey the stator clamped by the fixture 31 and place it in the storage box 6 for storage, so as to ensure the normal progress of continuous processing. Moreover, the guide plate 20 limits the stator during conveyance. After the stator during conveyance moves to the other side of the conveyor belt 19, it falls on the blanking plate 21 and slides into the storage box 6 on the blanking plate 21, realizing the collection of the stator that meets the qualified standard after magnetization.

[0077] As an embodiment, as Figure 19 shown, two support frames 22 are fixedly connected to the top of the support plate 2. Both of the two support frames 22 are in the shape of "丄", which is convenient for fixing and more convenient for cooperating with the magnetization cylinder 7 to work. The two support frames 22 are respectively located on both sides of the two magnetization cylinders 7. The top of the opposite sides of the two support frames 22 are fixedly connected with limiting frames 23. The opposite sides of the two limiting frames 23 are fixedly connected with tracks 24. The tracks 24 on the two limiting frames 23 are respectively slidably connected with sliding frames 25. The top of the two sliding frames 25 are fixedly connected with a top plate 26. One side of one of the limiting frames 23 is fixedly connected with a first hydraulic push rod 27. The first hydraulic push rod 27 is connected to the power supply and the controller. The output end of the first hydraulic push rod 27 passes through the limiting frame 23 and is fixedly connected to one side of the sliding frame 25. A second hydraulic push rod 28 is fixedly connected to the top plate 26. The second hydraulic push rod 28 is connected to the power supply and the controller. The output end of the second hydraulic push rod 28 is fixedly connected with an adjusting plate 29. The adjusting plate 29 is located between the two support frames 22. Four clamping mechanisms 30 are fixedly connected to the bottom of the adjusting plate 29. Four fixtures 31 are fixedly connected to the driving ends of the four clamping mechanisms 30. The clamping mechanisms 30 are connected to the power supply and the controller. The clamping of the clamping mechanisms 30 and the fixtures 31 is prior art.

[0078] In this embodiment, through the first hydraulic push rod 27, the two sliding frames 25 can be pushed to slide back and forth on the two tracks 24 respectively, so as to drive the four clamping mechanisms 30 fixed to the bottom of the top plate 26 to move back and forth. Through the cooperation of the four clamping mechanisms 30, the material taking and placing and magnetization can be carried out synchronously, with higher efficiency. Through the second hydraulic push rod 28, the four clamping mechanisms 30 are driven to rise or fall synchronously, so that the magnetized stator can be clamped when taking materials. After the stator is placed in the magnetization cylinder 7 for magnetization, the magnetized stator is synchronously placed on the conveyor belt 19 for conveying and移出. According to the distances of the magnetization cylinder 7, the chute 63, the conveyor belt 19, the size of the stator, etc., the moving strokes of the first hydraulic push rod 27, the second hydraulic push rod 28, and the clamping mechanisms 30 are set in advance.

[0079] It should be noted that:

[0080] The position of the first contact 58 is the highest point of the support rod 47. The support rod 47 passes through the magnetization cavity 8 and is used for the fixture 31 to place the stator on the limiting plate 49.

[0081] The position of the second contact 59 is when the stator is placed in the magnetizing cylinder 7 for magnetization.

[0082] The position of the third contact 60 is for placing the stator into the detection coil 35 for detection. After the stator passes the detection, the servo motor 40 will reverse and drive the control contact 57 to move directly from the position of the third contact 60 to the position of the first contact 58, so as to facilitate the removal of the stator after magnetic inspection.

[0083] The position of the fourth contact 61 is such that if the stator fails the inspection, the support rod 47 continues to move downward to the position of the fourth contact 61, so that the stator disengages from the limit plate 49. After the stator disengages, the servo motor 40 reverses, driving the control contact 57 to move directly from the position of the fourth contact 61 to the position of the first contact 58.

[0084] The start and stop of the above positions adopt existing technologies, such as connecting corresponding sensors and controllers to the corresponding positions or setting the start and stop time of the servo motor 40 through a relay.

[0085] Working principle of the present invention:

[0086] The stator that needs to be magnetized is placed in the distribution tray 4, and the distribution tray 4 is driven to vibrate by the vibration motor 12, and the stators placed in the distribution tray 4 are sorted, so that the stators fit into the inner wall of the distribution tray 4 and move until they are discharged from the discharge port 15 and fall into the feed rack 17, slide down through the Y-shaped feed rack 17, and are diverted. After diversion, the stator is clamped by two of the four clamps 31, and placed on the magnetization cylinder 7 after clamping. After being placed, it returns to the top of the feed rack 17 for re-taking. The other two clamps 31 cooperate to move the magnetized stator and place it on the conveyor belt 19, and when the frame 44 drives the support rod 47 to rise, it will also rise through the pushing frame 75 to push the pushing rod 64. The pushing rod 64 rises in the chute 63 to push the stator at the branch end of the feed rack 17, and the auxiliary clamp 31 performs the clamping operation.

[0087] When the stator is clamped to the top of the magnetizing cylinder 7, the support rod 47 is located in the magnetizing cavity 8, and the top of the support rod 47 is located at the top of the magnetizing cylinder 7. The stator is placed on the top of the support rod 47 and limited by the limit plate 49. After placement, the support rod 47 is driven by the servo motor 40 to descend and enter the magnetizing cylinder 7 for magnetization operation. After magnetization, the support rod 47 continues to descend and stops after passing the detection coil 35. The detection coil 35 performs a magnetic inspection on the stator. After the magnetic inspection is passed, the support rod 47 rises, driving the stator to move in the opposite direction to the top of the magnetizing cylinder 7, and is clamped and removed by the clamp 31.

[0088] When the stator fails the inspection, the pushing block 39 at the bottom of the unqualified stator on one side is pushed close to the support rod 47 by the two-way electric push rod 38. When the support rod 47 continues to descend, the pushing block 39 contacts the bottom of the limit plate 49, pushing the limit plate 49 to slide up on the support rod 47, and the limit plate 49 pushes the stator to separate from the support rod 47. When both sides fail the inspection, the two-way electric push rod 38 controls the two pushing blocks 39 to move synchronously to the bottom of the two limit plates 49, and the detached stator falls into the frame 44 and falls into the storage frame 52 through the drop port 51.

[0089] It should be noted that the above is the complete operation process of the magnetizer, but it does not represent the entire protection scope of this application. It is only for the purpose of more clearly and completely recording the operation process of the magnetizer. However, the present invention only improves the structure of the magnetizer itself, and does not improve and protect the control, software and other programs. For example, the movement of the first hydraulic push rod 27 and the second hydraulic push rod 28 in the same direction is the existing technology, and the start and stop of the bidirectional electric push rod 38, the start and stop of the servo motor 40 and the signal transmission of the contact sensor 62 all use the existing technology. The start and stop signals can be installed at the corresponding position with corresponding sensors, including but not limited to contact sensors, infrared sensors, stroke sensors, light curtain sensors, etc., and relays can also be used for time control.

[0090] The present invention has the following technical effects.

[0091] 1. The present invention provides a servo motor 40, a first rotating rod 42, a second rotating rod 43 and a frame 44 to drive the support rod 47 to rise and fall, thereby facilitating the stator to be limited by the clamp 31 when the clamp 31 clamps the stator, and supporting the stator for subsequent magnetic inspection operations. By providing a first contact 58, a second contact 59, a third contact 60 and a fourth contact 61, the limit plate 49 on the support rod 47 is respectively stopped at different positions to meet the different requirements of magnetization and magnetic inspection.

[0092] 2. The present invention utilizes a limit frame 23, a track 24, a clamping mechanism 30, and a clamp 31. Two sets of clamping mechanisms 30 (each set comprising two clamps 31) enable simultaneous loading and unloading of materials and magnetization operations, thereby shortening stator processing time and improving magnetization efficiency. Furthermore, by providing a penetration slot 32, a detection slot 33, a fixing frame 34, and a detection coil 35, magnetic inspection is performed immediately on the magnetized stator, eliminating the need for a subsequent separate magnetic inspection of the stator and allowing unqualified products to be eliminated immediately.

[0093] 3. The present invention sets a feeding rack 17 on the top of the box body 1, thereby diverting the conveyed motor stator and conveying it to the two branch ends of the feeding rack 17, and cooperates with the clamp 31 to clamp it and put it into the magnetization cylinder 7 for magnetization operation, which is more efficient. By setting the inner tube 9, the outer tube 10, the first spring 11 and the feeding slope 13, the distribution tray 4 is driven to vibrate, so that the stators placed in the distribution tray 4 are discharged from the discharge port 15 in an orderly manner, realizing automatic, continuous and reliable loading of bulk stators, and providing a stable foundation for subsequent efficient magnetization.

[0094] 4. The present invention uses the baffle 48, the limit plate 49, the first tension spring 50, the bidirectional electric push rod 38 and the push block 39 to push the unqualified products off the support rod 47 after magnetic inspection and store them in the storage frame 52, thereby ensuring the continuous processing of qualified products. Through the push rod 64, the third spring 65, the push frame 75 and the fixed plate 76, when the clamp 31 moves to the top of the feed rack 17 to pick up materials, the stator in the feed rack 17 is pushed upwards, making it convenient for the clamp 31 to clamp the smaller stator to pick up materials.

[0095] Although the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description is not intended to limit the present invention. Various modifications and substitutions of the present invention will be readily apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention shall be defined by the appended claims.
