Description

Technical Field

[0001] The 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, such as Figure 1 The rotor shown has a main body section 101 and end portions 102 formed at both ends of the main body section 101. The end portions 102 are used for assembly, and their diameter is smaller than the diameter of the main body section 101. Each end portion is formed with a plurality of steps, and correspondingly, the two ends of the rotor have a plurality of step surfaces. The rotor is magnetized by a magnetizing device. During magnetization, the rotor is placed in the magnetizing device as a whole. After magnetization, the magnetization amount is detected, and the ends of the rotor are demagnetized to prevent the rotor ends from having magnetism that affects the performance of the rotor. 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, such as the magnetization, demagnetization and surface magnetism integrated equipment disclosed in CN202410565961.0 and the processing device for rotor production disclosed in CN202321016114, both of which adopt the 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 heights of the main sections of the rotors may be different, and the current rotor magnetic processing magnetic device basically sets the position of the rotor 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

DETAILED DESCRIPTION

[0038] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0039] like Figure 2 As shown, an embodiment of the present invention provides a turntable rotor magnetic processing device, including 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. Usually, the processing stations include a loading station, a magnetization station, a magnetization amount detection station, a surface magnetization station, a demagnetization station, and a material 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 transfer the rotor to the surface magnetization station, and the magnetic steel on the rotor is checked to see if there is any shortage or unsaturation; after the surface magnetization is completed, the turntable rotates to send the rotor to the demagnetization station to demagnetize the end of the rotor, and 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, the demagnetization station, and the unloading station are integrated in one station, which is defined as a loading and unloading integrated station, and 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 the structures of other processing stations will not be described in detail.

[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 driving 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 table 10 and is provided with a preset height. A plurality of through-holes 211 are provided along a circular line adjacent to the outer peripheral surface on the top surface of the turntable 21. 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 loading and unloading integrated station. The four through-holes 211 corresponding to the four stations on the turntable 21 are provided at equal intervals and distributed in four directions. The turntable driving mechanism is mounted on the top surface of the machine table 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, and is used to carry and fix 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 and is connected to the bearing hole 2211, and the tray 2 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 is separated from the support for the rotor; preferably, the pusher 222 is a cylinder, and the tray 221 is connected to the piston end of the cylinder. Further, 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, and the tray 221 is installed on the slide rail 223, and is guided to slide by the slide rail 223. 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 that of the main section of the rotor, and the small hole section has a diameter equivalent to that of the end section of the rotor. This facilitates 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 material 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 seat 31, a material receiving barrel 32 and a lifting drive 33. The fixed seat 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 seat 31 and is driven to move up and down by the lifting drive 33. It can be understood that the lifting drive 33 preferably adopts a cylinder. Further, the fixed seat 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 erected 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 member 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 member 33 adopts a cylinder, and its piston rod passes upward through the mounting plate 315 and is connected to the lifting plate 316, so as to drive the lifting plate 316 to rise and fall along the guide column 314. The receiving barrel 32 is used to receive the rotor, and the end of the rotor can 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 together with the lifting and falling of the lifting plate 316. Furthermore, the receiving mechanism 30 includes a sensor 34 arranged on the top surface of the top plate 312 to monitor the lifting height 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 the rotor is delivered 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 arranged between the fixed plate 421 and the lifting slide 422. The track is used to guide the lifting slide 422 to lift and slide, and the lifting drive mechanism is used to drive the lifting slide 422 to lift and lower 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 arranged on the screw of the screw motor, and the lifting slide 422 is driven to rise and fall by the rotation of the screw.

[0045] In this embodiment, the lifting slide plate 422 is L-shaped, including a lifting section slidably matched 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 seat 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 rise and fall 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 can be installed on the fixed seat 431 in a transverse manner, and the transverse direction is perpendicular to the lifting direction. The height measuring mechanism 44 includes a height measuring sensor, which is installed on the transverse plate 432, and its sensing head is vertically downward to detect the height of the rotor carried on the tray 221; preferably, the height measuring sensor adopts a contact sensor, including a contact rod 441 extending downward. During detection, the transverse plate 432 moves horizontally to drive the height measuring sensor to be located above the rotor, and then the lifting slide 422 moves downward. When the contact rod 441 contacts the end face of the rotor, it is triggered to detect the height of the rotor, and 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 position 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, it is necessary to start the rotor to rotate so that it is at an accurate demagnetization angle, which also corresponds to the gripping angle required for material unloading. The surface measuring mechanism 45 is installed on the transverse plate 432. It uses a sensor with a 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 circumferential surface reflects the signal back to the surface measuring mechanism 45 accordingly, thereby confirming whether the rotor is in an accurate 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 circumferential surface orientation of the rotor is accurate. Otherwise, the rotor needs to be driven to rotate to the corresponding accurate position. It can be understood that the surface measuring mechanism 45 can also adopt a contact sensor, and the surface measuring mechanism 45 is driven to contact the corresponding contact position on the rotor surface by the transverse movement of the transverse movement plate 432 to determine the circumferential surface position of the rotor.

[0048] The demagnetization unit 46 is used to demagnetize the end of the rotor. The demagnetization unit 46 is installed on the lifting slide 422. The lifting and lowering of the lifting slide 422 drives the demagnetization unit 46 to move along the axial direction of the rotor to achieve demagnetization of the rotor end. The demagnetization unit 46 includes a demagnetization cover, and a demagnetization channel 461 is provided on the demagnetization cover for demagnetizing the rotor end after being inserted into the rotor end. The demagnetization cover is installed on the horizontal section of the lifting slide 422. It can be understood that a through hole is correspondingly formed on the horizontal section and is correspondingly connected to the demagnetization channel 461. When demagnetizing the rotor end, the lifting slide 422 drives the demagnetization cover to be sleeved on the end of the rotor to demagnetize the rotor end.

[0049] The demagnetization detection mechanism 47 is used to detect the demagnetization amount of the rotor end. If the rotor end meets the demagnetization requirement, it is qualified, otherwise the demagnetization is unqualified. The demagnetization detection mechanism 47 is installed on the transverse plate 432 and has a detection rod. The detection rod is arranged horizontally, and the detection head of the detection rod faces the circumference of the rotor to detect the magnetic amount of the circumference of the rotor end. During detection, the demagnetization detection mechanism 47 moves horizontally to the detection distance corresponding to the rotor surface through the transverse plate 432 to accurately detect 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 the 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 mounted on the bottom surface of the lifting plate 316. The output shaft of the driving motor 491 extends upward and is connected to the receiving barrel 32 through the conveyor belt structure. Thus, the output shaft of the driving motor 491 rotates, which drives the 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 can be understood that the demagnetization mechanism 40 also includes a telecommunication processing unit. When 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, and the specific process is as follows:

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

[0055] B. The rotor itself is magnetic as a whole or the rotor is brought to other processing stations in sequence after the turntable rotates, and the rotor is magnetic as a whole. The rotor returns to the loading and unloading integrated station, and the surface measuring mechanism 45 is started to detect the circumferential direction 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 49 is started to drive the rotor to rotate and adjust the circumferential direction of the rotor;

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

[0057] D. Calculate the required descending stroke of the demagnetization unit 46 according to the height of the rotor detected by the height measuring mechanism 44;
