Description

Technical Field

[0001] The present invention relates to the technical field of rotor magnetization, and in particular to a turntable rotor magnetic processing device and a demagnetization method thereof. Background Art

[0002] During the manufacturing process of the motor rotor, the main section of the rotor needs to be magnetized to make it magnetic. Figure 1 The rotor shown has a main section 101 and end sections 102 formed at either end of the main section 101. The end sections 102 are used for assembly and have a smaller diameter than the main section 101. Each end section has several steps, corresponding to the number of stepped surfaces at each end of the rotor. The rotor is magnetized using a magnetizing device. During magnetization, the entire rotor is placed in the device. After magnetization, the magnetization level is measured, and the rotor ends are demagnetized to prevent any magnetism from affecting the rotor's performance. The existing magnetization process of the rotor generally includes loading, magnetization, magnetization amount detection, surface magnetism detection (i.e. detection of the number of magnetic steels), demagnetization, and unloading processes; the processing production line adopts assembly line type and turntable type, among which the turntable type occupies less space and is more compact as a whole, which is more conducive to processing operations and is widely used in the industry. For example, the magnetization, demagnetization and surface magnetism integrated equipment disclosed in CN202410565961.0 and the processing device for rotor production disclosed in CN202321016114 both adopt a turntable structure. In the above two patents, the arrangement thereof is There are many overall workstations, such as a separate workstation for loading, a workstation for magnetizing, and a workstation for demagnetizing, which makes the overall structure relatively complex. In addition, even for the same batch of rotors, the height of the main section of the rotor may be different. The current rotor magnetic processing magnetic device basically sets the rotor position in the magnetizing device during magnetization, and sets the demagnetization stroke of the demagnetization device during demagnetization, but cannot adjust the stroke accordingly according to the different rotor lengths. Therefore, the existing rotor magnetic processing magnetic device may have length deviations for different rotors, resulting in low demagnetization accuracy. Summary of the Invention

[0003] In view of the above, it is necessary to provide a turntable rotor magnetic processing device that can simplify the structure and improve the demagnetization accuracy.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A turntable rotor magnetizing device includes a machine platform, a turntable structure disposed on the machine platform, and a plurality of processing stations distributed around the turntable structure.

[0010] Furthermore, the material receiving mechanism includes a fixed seat, the fixed seat includes a support rod, a top plate, a guide column fixedly connected to the bottom surface of the top plate, a mounting plate fixedly connected to the bottom surface of the guide column, and a lifting plate slidably mounted on the guide column; the support rod is fixedly erected on the machine platform to support the top plate, and a through hole is provided on the top plate for the material receiving barrel to pass through, the lifting drive member is fixedly mounted on the mounting plate to drive the lifting plate to rise and fall, and the material receiving barrel is rotatably mounted on the lifting plate, and the demagnetization mechanism includes a rotor driving mechanism, the rotor driving mechanism includes a driving motor and a conveyor belt structure, the driving motor is fixedly mounted on the lifting plate, and the output shaft of the driving motor is connected to the material receiving barrel through the conveyor belt structure.

[0011] Furthermore, the tray structure includes a slide rail, which is installed on the top surface of the turntable and extends to the corresponding through-holes. The tray is installed on the slide rail and is guided to slide by the slide rail.

[0012] Furthermore, the frame includes support frames relatively arranged on both sides of the turntable and a frame connected between the support frames, the frame spanning the top of the turntable, the lifting guide seat includes a fixed plate and the lifting slide, the fixed plate is fixedly installed on the frame, and the lifting slide can be lifted and lowered on the fixed plate, the transverse guide seat includes a fixed seat and the transverse plate, the fixed seat is fixedly connected to the lifting slide, and the transverse plate can be transversely installed on the fixed seat.

[0013] Furthermore, the lifting slide includes a lifting section that is slidably matched with the fixed plate and a horizontal section vertically connected to one end of the lifting section, and the demagnetization unit is installed on the horizontal section.

[0014] In addition, the present invention provides a demagnetization method for the turntable rotor magnetic processing device.

[0015] The demagnetization method of the turntable rotor magnetic processing device has the following specific process:

[0016] A. The turntable moves to the loading and unloading integrated station, the rotor is loaded, the receiving barrel of the receiving mechanism rises to receive the rotor, then the barrel descends, and the tray supports the rotor;

[0017] B. The surface measurement mechanism is activated to detect the circumferential orientation of the rotor to determine whether the circumferential surface of the rotor is accurately at the required demagnetization angle. If it is not accurately at the required demagnetization angle, the rotor driving mechanism is activated to drive the rotor to rotate and adjust the circumferential orientation of the rotor;

[0022] G. The demagnetization unit rises and moves out of the top end of the rotor, and the rotor is removed.

[0023] Furthermore, a bearing hole is formed in the center of the tray and a notch is formed on the outer periphery of the tray and is connected to the bearing hole; in step A, when the rotor is loaded, the receiving barrel rises and passes through the through-hole of the turntable and the bearing hole of the tray to receive the rotor, and the end of the rotor is inserted into the receiving barrel. After receiving the rotor, the receiving barrel begins to descend, and after descending to a certain height, the main section of the rotor will be mounted on the tray, and the tray supports the rotor.

[0024] Furthermore, the height measuring sensor adopts a contact sensor, including a contact rod extending downward. In step C, during detection, the transverse plate moves horizontally to drive the height measuring sensor above the rotor, and then the lifting slide moves downward. When the contact rod contacts the end face of the rotor, it is triggered to detect the height of the rotor.

[0025] Furthermore, the surface measuring mechanism adopts a signal receiving sensor. In step B, it transmits a signal to the circumferential surface of the rotor. An axially extending detection groove is provided on the circumferential surface of the rotor. The signal emitted by the surface measuring mechanism reaches the corresponding detection groove to confirm the accuracy of the circumferential surface orientation of the rotor.

[0026] The beneficial effects of the present invention are:

[0027] The turntable rotor magnetic processing device provided by the present invention is capable of detecting the circumferential orientation and height of the rotor during demagnetization by providing a surface measuring mechanism and a height measuring mechanism through a demagnetization mechanism, thereby ensuring the accuracy of the demagnetization position of the rotor and the demagnetization height required for the demagnetization unit to move to the rotor end. In this way, the demagnetization effect of the rotor terminal can be ensured, and corresponding demagnetization strokes can be performed according to rotors of different heights. In addition, the turntable rotor magnetic processing device of the present invention integrates the functions of the loading station, demagnetization station, and unloading station into one station, greatly simplifying the structure of the device.

DETAILED DESCRIPTION

[0038] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0039] like Figure 2 As shown, an embodiment of the present invention provides a turntable rotor magnetic processing device, comprising a machine table 10, a turntable structure 20 arranged on the machine table 10, and a plurality of processing stations distributed around the turntable structure 20. The turntable structure 20 rotates to drive the rotor to enter the corresponding processing station for processing in sequence. Generally, the processing stations include a loading station, a magnetization station, a magnetization amount detection station, a surface magnetization station, a demagnetization station, and an unloading station. The processing process is to install the rotor to be processed on the turntable at the loading station; then the turntable rotates to send the rotor to the magnetization station for magnetization; after the magnetization is completed, the turntable rotates to send the rotor to the magnetization amount detection station, after the magnetization amount detection is completed, the turntable rotates to send the rotor to the surface magnetization station to check whether the magnetic steel on the rotor is missing or unsaturated; after the surface magnetization is completed, the turntable rotates to send the rotor to the demagnetization station to demagnetize the end of the rotor, after the demagnetization is completed, the turntable rotates to send the rotor to the unloading station to remove the rotor. In the embodiment of the present invention, the structure of the turntable rotor magnetizing device is improved, and the functions of the loading station, demagnetization station, and unloading station are integrated into one station, which is defined as a loading and unloading integrated station. It can also be applied to conventional rotor magnetizing devices. The embodiment of the present invention will focus on the loading and unloading integrated station structure, and will not elaborate on the structures of other processing stations.

[0040] See also Figure 3 、 Figure 4The turntable structure 20 includes a turntable 21, a plurality of tray structures 22 arranged on the turntable 21, and a turntable drive mechanism (not shown) arranged on the bottom surface of the turntable 21 for driving the turntable 21 to rotate. The turntable 21 is rotatably mounted on the top surface of the machine 10 and is provided with a preset height. A plurality of through-holes 211 are provided on the top surface of the turntable 21 adjacent to the outer circumference along a circular line. The number of through-holes 211 corresponds to the number of set processing stations. The turntable rotor magnetic processing device shown in this embodiment is provided with four processing stations, one of which is a combined loading and unloading station. The four through-holes 211 corresponding to the four stations on the turntable 21 are evenly spaced and distributed in four directions. The turntable drive mechanism is mounted on the top surface of the machine 10, supports the center of the turntable 21, and can drive the turntable 21 to rotate according to the required angle.

[0041] The tray structure 22 is arranged corresponding to the through hole 211 for carrying and fixing the rotor; the tray structure 22 includes a tray 221 and a pusher 222. The tray 221 is slidably arranged on the top surface of the turntable 21. The tray 221 is connected to one end of the pusher 222 and is pushed to slide on the top surface of the turntable 21 by the pusher 222. A bearing hole 2211 is formed in the center of the tray 221 and a notch 2212 is formed on the outer periphery of the tray 221 to communicate with the bearing hole 2211. When the tray 21 slides to the processing station, the bearing hole 2211 is aligned with the through hole 211, and the rotor can be received. That is, the end of the rotor is inserted into the bearing hole 2211, and the tray 221 supports the main section of the rotor. When the tray 221 slides away from the processing station, the bearing hole 2211 and the through hole 211 are staggered, and the tray 221 is disengaged from the rotor at the notch 2212, and the tray 221 loses its support for the rotor. Preferably, the pusher 222 is a cylinder, and the tray 221 is connected to the end of the piston of the cylinder. Furthermore, the tray structure 22 includes a slide rail 223, which is installed on the top surface of the turntable 21 and extends to the corresponding through hole 211. The tray 221 is installed on the slide rail 223 and guided by the slide rail 223 to slide. Preferably, the bearing hole 2211 is a stepped hole with a large hole section and a small hole section. The large hole section has a diameter equivalent to the main section of the rotor, and the small hole section has a diameter equivalent to the end section of the rotor. This makes it easier for the rotor to be stably inserted into the bearing hole 2211.

[0042] The turntable rotor magnetic processing device includes a loading and unloading station structure corresponding to the loading and unloading integrated station. The loading station structure includes a receiving mechanism 30 located below the turntable 21 and a demagnetization mechanism 40 located above the turntable 21. Figure 2 、 Figure 5The material receiving mechanism 30 includes a fixed base 31, a material receiving barrel 32, and a lifting drive 33. The fixed base 31 is fixedly mounted on the top surface of the machine 10 and is located below the turntable 21. The material receiving barrel 32 is movably mounted on the fixed base 31 and is driven to move up and down by the lifting drive 33. It can be understood that the lifting drive 33 is preferably a cylinder. Furthermore, the fixed base 31 includes a support rod 311, a top plate 312, a guide column 314 fixedly connected to the bottom surface of the top plate 312, a mounting plate 315 fixedly connected to the bottom surface of the guide column 314, and a lifting plate 316 slidably mounted on the guide column 314; the support rod 311 is fixedly mounted on the top surface of the machine 10 to support the top plate 312. The top plate 312 is provided with a through hole 3121 for the material receiving barrel 32 to pass through. The lifting drive 33 is fixedly mounted on the bottom surface of the mounting plate 315 and is used to drive the lifting plate 316 to rise and fall. The lifting drive 33 is a pneumatic cylinder, whose piston rod extends upward through the mounting plate 315 and connects to the lifting plate 316, thereby driving the lifting plate 316 to rise and fall along the guide column 314. The receiving barrel 32 is used to receive the rotor, allowing the end of the rotor to be inserted into the receiving barrel 32. The outer diameter of the receiving barrel 32 is smaller than the aperture of the through hole 211 of the turntable 21 and the aperture of the bearing hole 2211 of the tray 221. The receiving barrel 32 is rotatably mounted on the lifting plate 316 and rises and falls in conjunction with the rise and fall of the lifting plate 316. Furthermore, the receiving mechanism 30 includes a sensor 34 disposed on the top surface of the top plate 312 to monitor the elevation of the receiving barrel 32.

[0043] When the rotor is loaded, the receiving barrel 32 rises and passes through the through-hole 211 of the turntable 21 and the bearing hole 2211 of the tray 221 to receive the rotor. The end of the rotor is inserted into the receiving barrel 32. The receiving barrel 32 begins to descend after receiving the rotor. After descending to a certain height, the main body of the rotor will be carried on the tray 221. The tray 221 supports the rotor, so that the receiving mechanism 30 receives the rotor at a certain height position, and then delivers the rotor to the tray 221. The rotor is positioned at a height position on the turntable 21 through the reception by the tray 221.

[0044] See also Figure 6-Figure 8The demagnetization mechanism 40 is used to accurately demagnetize the upper end of the rotor. The demagnetization mechanism 40 includes a frame 41, a lifting guide seat 42, a transverse guide seat 43, a height measuring mechanism 44, a surface measuring mechanism 45, a demagnetization unit 46 and a demagnetization detection mechanism 47; the frame 41 is set up on the machine platform 10, including support frames 411 relatively arranged on both sides of the turntable 21 and a frame 412 connected between the support frames 411, and the frame 412 spans above the turntable 21. The lifting guide seat 42 is installed on the frame 41, and includes a fixed plate 421 and a lifting slide 422. The fixed plate 421 is fixedly installed on the frame 412, and the lifting slide 422 can be lifted and lowered on the fixed plate 421. It can be understood that a track and a lifting drive mechanism are provided between the fixed plate 421 and the lifting slide 422. The track is used to guide the lifting slide 422 to move up and down, and the lifting drive mechanism is used to drive the lifting slide 422 to move up and down relative to the fixed plate 421. In this embodiment, the lifting drive mechanism preferably adopts a screw drive structure. The screw motor is installed on the fixed plate 421, and the lifting slide 422 is equipped with a screw sleeve which is sleeved on the screw of the screw motor. The lifting slide 422 is driven to move up and down by the rotation of the screw.

[0045] In this embodiment, the lifting slide 422 is L-shaped, including a lifting section that slides with the fixed plate 421 and a horizontal section vertically connected to one end of the lifting section, and the demagnetization unit 46 is installed on the horizontal section.

[0046] The transverse guide 43 includes a fixed seat 431 and a transverse plate 432. The fixed seat 431 is fixedly connected to the lifting slide 422 and is driven to move upward and downward by the lifting slide 422. Specifically, in this embodiment, the fixed seat 431 is fixedly connected to the bottom side of the horizontal section of the lifting slide 422 and is located outside the bottom surface of the horizontal section. The transverse plate 432 is mounted on the fixed seat 431 for transverse movement, with the transverse movement direction perpendicular to the lifting direction. The height measurement mechanism 44 includes a height measurement sensor. The height measurement sensor is mounted on the transverse plate 432, with its sensor head pointing vertically downward, for detecting the height of the rotor supported on the tray 221. Preferably, the height measurement sensor is a contact sensor including a downwardly extending contact rod 441. During detection, the transverse plate 432 moves laterally, driving the height measurement sensor above the rotor. The lifting slide 422 then moves downward. When the contact rod 441 contacts the end face of the rotor, the sensor is triggered to detect the height of the rotor. The length of the rotor main section and the length of the rotor end can be detected.

[0047] The surface measuring mechanism 45 is used to detect the orientation of the rotor's circumferential surface to determine whether the rotor's circumferential surface is accurately at the required demagnetization angle. If it is not accurately oriented, the rotor needs to be started to rotate so that it is at the precise demagnetization angle, which also corresponds to the gripping angle required for blanking. The surface measuring mechanism 45 is installed on the transverse plate 432. It uses a sensor with the sensing head facing the horizontal direction to sense the corresponding sensing position on the rotor's circumferential surface. In this embodiment, the surface measuring mechanism 45 uses a signal receiving sensor, which transmits a signal to the rotor's circumferential surface, and the corresponding signal is reflected back to the surface measuring mechanism 45 on the circumferential surface, thereby confirming whether the rotor is in a precise circumferential surface orientation position. Specifically, an axially extending detection groove (which can be an assembly groove or a process groove) is provided on the circumferential surface of the rotor. The signal sent by the surface measuring mechanism 45 to the corresponding detection groove can confirm that the rotor's circumferential surface orientation is accurate. Otherwise, the rotor needs to be driven to rotate to the corresponding precise position. It is understandable that the surface measuring mechanism 45 may also adopt a contact sensor, and the transverse plate 432 is moved transversely to drive the surface measuring mechanism 45 to contact the corresponding contact position on the rotor surface to determine the circumferential surface position of the rotor.

[0048] Demagnetization unit 46 is used to demagnetize the rotor ends. It is mounted on a lift plate 422. The lift plate 422 raises and lowers the demagnetization unit 46, causing it to move axially along the rotor to demagnetize the rotor ends. Demagnetization unit 46 includes a demagnetization cover with a demagnetization channel 461 for insertion into the rotor end to demagnetize the rotor. The cover is mounted on a horizontal section of the lift plate 422. As will be understood, corresponding through-holes are formed in the horizontal section to communicate with the demagnetization channel 461. To demagnetize the rotor ends, the lift plate 422 drives the demagnetization cover to fit over the rotor ends, demagnetizing the rotor ends.

[0049] The demagnetization detection mechanism 47 is used to detect the demagnetization amount at the rotor end. If the rotor end meets the demagnetization requirements, it is qualified; otherwise, the demagnetization fails. The demagnetization detection mechanism 47 is mounted on the transverse plate 432 and includes a detection rod. The detection rod is arranged horizontally, with the detection head of the detection rod facing the circumference of the rotor to detect the magnetic amount of the circumferential surface of the rotor end. During testing, the transverse plate 432 moves horizontally, and the demagnetization detection mechanism 47 moves horizontally to the detection distance corresponding to the rotor surface, accurately detecting the demagnetization effect of the rotor end.

[0050] Furthermore, the demagnetization mechanism 40 includes a fine-tuning mechanism 48 for fine-tuning the lateral movement of the demagnetization detection mechanism 47 to improve the accuracy of the detection. The fine-tuning mechanism 48 can adopt a bolt threaded sleeve structure, which can limit the bolt to be rotatable (that is, it cannot move forward and backward). Rotating the bolt can realize the sliding of the threaded sleeve relative to the bolt. The demagnetization detection mechanism 47 is installed on the threaded sleeve structure. The sliding of the threaded sleeve drives the demagnetization detection mechanism 47 to move, thereby realizing fine-tuning of the lateral movement of the demagnetization detection mechanism 47. Its specific structure is not described in detail in the present invention.

[0051] It can be understood that the demagnetization mechanism 40 includes a rotor driving mechanism 49 for driving the rotor to rotate. Please refer to Figure 5 The rotor driving mechanism 49 includes a driving motor 491 and a conveyor belt structure. The driving motor 491 is fixedly installed on the bottom surface of the lifting plate 316. The output shaft of the driving motor 491 extends upward and is connected to the material receiving barrel 32 through the conveyor belt structure. Therefore, the output shaft of the driving motor 491 rotates, which drives the material receiving barrel 32 to rotate, and then drives the rotor to rotate, thereby realizing the adjustment of the rotor angle, that is, the adjustment of the circumferential direction position.

[0052] It is understandable that the demagnetization mechanism 40 further includes a telecommunication processing unit. Upon receiving a signal from a sensor or other device, the telecommunication processing unit immediately sends a processing signal to drive the corresponding component to operate.

[0053] The present invention provides a demagnetization method for the turntable rotor magnetic processing device, the specific process of which is as follows:

[0054] A. The turntable moves to the loading and unloading integrated station, the rotor is loaded, the receiving cylinder 32 of the receiving mechanism 30 rises to receive the rotor, then the receiving cylinder 32 descends, and the tray 221 supports the rotor;

[0055] B. The rotor itself is magnetic or the rotor is brought to other processing stations in sequence by the turntable. The rotor is magnetic as a whole. The rotor returns to the loading and unloading integrated station. The surface measuring mechanism 45 is activated to detect the orientation of the rotor's circumferential surface to determine whether the rotor's circumferential surface is accurately at the required demagnetization angle. If it is not accurately at the required demagnetization angle, the rotor driving mechanism 49 is activated to drive the rotor to rotate and adjust the rotor's circumferential surface orientation.

[0056] C. The height measuring mechanism 44 is activated to detect the height of the rotor;

[0057] D. Calculate the required descending distance of the demagnetization unit 46 based on the height of the rotor detected by the height measuring mechanism 44;

[0058] E. Start the demagnetization unit 46. The demagnetization unit 46 is lowered and placed on the top of the rotor to demagnetize the top of the rotor. After demagnetization is completed, the demagnetization unit 46 is closed.

[0059] F. Start the demagnetization detection mechanism 47 to detect the demagnetization amount of the rotor end. If the rotor end meets the demagnetization requirement, it is qualified. Otherwise, the demagnetization unit 46 needs to demagnetize again until it passes.

[0060] G. The demagnetization unit 46 rises and moves out of the top end of the rotor, and the rotor is removed.

[0061] The turntable rotor magnetic processing device provided by the present invention is equipped with a surface measuring mechanism 45 and a height measuring mechanism 44 through the demagnetization mechanism 40. These can detect the circumferential orientation of the rotor and the height of the rotor during demagnetization, thereby ensuring the accuracy of the demagnetization position of the rotor and the demagnetization height required for the demagnetization unit 46 to move the rotor end. In this way, the demagnetization effect of the rotor terminal can be ensured, and the demagnetization stroke can be adjusted accordingly according to the rotor height. In addition, the turntable rotor magnetic processing device of the present invention integrates the functions of the loading station, demagnetization station, and unloading station into one station, greatly simplifying the structure of the device.

[0062] The above-described embodiments merely illustrate the implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
