Description

Technical Field

[0001] The utility model relates to the technical field of rotor motor production, in particular to a rotor core magnet installation device. Background Art

[0002] A rotor motor is a type of motor that works based on electromagnetic induction. A rotor motor is generally divided into a rotor and a stator. The stator is the fixed part, and the rotor is the rotating part. Magnets are attached to the rotor core, and the rotor is driven to rotate under the electromagnetic induction on the stator.

[0003] Since the magnet is divided into an S pole and an N pole, and the S pole and the N pole will automatically adsorb each other, when sticking the magnet to the iron core, you need to first apply glue on the outer edge of the iron core, and then glue the magnet to the iron core with glue.

[0004] The existing process of placing the iron core at the glue position is generally performed manually. During the manual placement of the magnets, deviations may occur in the placement of the magnets. If the placement of one of the magnets deviates, the magnetic field generated by the magnet will not correspond to the magnetic field generated by the current coil, thereby causing the rotor to rotate unsmoothly.

[0032] The rotating shaft 13 is fixedly connected with a 90-degree fan-shaped plate 19, and the frame 1 is fixedly connected with a photoelectric sensor 20 used in conjunction with the fan-shaped plate 19. The fan-shaped plate 19 shields the photoelectric sensor 20. When the fan-shaped plate 19 rotates to a position where the shielding of the photoelectric sensor 20 is cancelled, the rotating shaft 13 stops rotating, and the rotating shaft 13 rotates 90 degrees at this time.

[0033] A limiting component installed on one side of the positioning component and capable of approaching or moving away from the positioning component, the limiting component is used to limit one end of the iron core, the limiting component includes a pin 15 slidably connected to the frame 1 via a push cylinder 14 and coaxially arranged with the rotating shaft 13, the push cylinder 14 drives the pin 15 to move toward the rotating shaft 13, thereby limiting the iron core on the rotating shaft 13;

[0034] An auxiliary component is arranged between the positioning component and the limiting component, and the auxiliary component includes a support plate 17 which is slidably connected to the frame 1 through a material auxiliary cylinder 16. The support plate 17 is provided with an arc-shaped auxiliary groove 18 which fits the outer edge surface of the iron core. The material auxiliary cylinder 16 provides power for the support plate 17 to move up and down. Under the action of the material auxiliary cylinder 16, the support plate 17 is moved close to the outer edge surface of the iron core, and the auxiliary groove 18 supports the iron core.

[0035] A magnet transfer structure is installed on one side of the iron core fixed structure for separating and transferring the magnets. The magnets are separated into S poles and N poles on the magnet transfer structure, and the position of the magnets is moved under the action of the magnet transfer structure.

[0036] The magnet transfer structure includes a carrier platform 3 fixedly connected to the frame 1, a magnet separation jig 4 installed on the carrier platform 3, the magnet separation jig 4 separates the magnet into an S pole and an N pole, and the magnet is located in a magnet receiving groove 6, and a magnet pushing cylinder 5 used in conjunction with the magnet separation jig 4, the carrier platform 3 is provided with a magnet receiving groove 6 located below the magnet separation jig 4, the magnet pushing cylinder 5 is fixedly connected with a push rod 7 inserted into the magnet receiving groove 6, and the push rod 7 pushes the magnet in the magnet receiving groove 6.

[0037] The magnet transfer structure also includes a magnet adsorption component connected to the driving structure, and the magnet adsorption component includes a connecting plate 8 used in conjunction with the driving structure, and a vacuum cylinder 9 installed on the connecting plate 8 for adsorbing the magnet. The vacuum cylinder 9 has an arc groove 10 at the air nozzle that fits the outer edge surface of the magnet. The arc groove 10 is connected to the magnet receiving groove 6, and the arc groove 10 closes the opening of the magnet receiving groove 6. During the sliding process between the magnet and the magnet receiving groove 6, the magnet is located directly below the air nozzle, and the magnet is adsorbed under the action of the vacuum of the air nozzle.

[0038] The connecting plate 8 is connected to the magnet front and rear cylinders 12 via the magnet lifting cylinder 11. The output shaft of the magnet front and rear cylinders 12 is fixedly connected to the vacuum cylinder 9. The magnet front and rear cylinders 12 and the magnet lifting cylinder 11 adjust the position of the vacuum cylinder 9. On the one hand, the air nozzle of the vacuum cylinder 9 is connected to the magnet receiving groove 6, and on the other hand, the magnet adsorbed by the air nozzle can match the rotating iron core.

[0039] A glue coating structure is installed above the core fixing structure and is used to coat glue along the outer edge of the core. The glue coating structure coats the glue at a suitable position so that the magnet can be fixed at a corresponding position on the outer edge of the core under the action of the glue.

[0040] The glue coating structure includes a glue gun connected to the driving structure via upper and lower glue cylinders 21. The glue gun includes a positioning sensor 22 for positioning the glue coating position and a glue injector 23 for glue coating. The glue outlet of the glue injector 23 is located on the extension line of the positioning sensor 22. The positioning sensor 22 limits the position of the glue gun.

[0041] The glue injector 23 and the extension line of the positioning sensor 22 are at an angle of 30-45 degrees. The glue injector 23 is inclined at the above angle to apply glue, so that the glue can be better applied to the outer edge surface of the iron core.

[0042] A driving structure is arranged in the frame 1 for driving the glue coating structure and the magnet transfer structure. The driving structure drives the glue coating structure and the magnet transfer structure to move the glue coating structure along the axial direction of the iron core, and also moves the magnet transfer structure from the magnet separation fixture 4 to just above the iron core.

[0043] The driving structure includes a support frame 24 fixedly connected to the frame body 1, and a driving motor 25 is fixedly connected to the support frame 24. The output shaft of the driving motor 25 is threadedly connected to the connecting plate 8, and the connecting plate 8 is slidingly connected to the support frame 24. The driving motor 25 drives the connecting plate 8 via the thread, so that the magnet transfer structure can translate along the output shaft of the driving motor 25.

[0044] The driving structure also includes a stepper motor 26 fixedly connected to the support frame 24. The output shaft of the stepper motor 26 is connected to the upper and lower glue cylinders 21 via a transmission belt 27. The stepper motor 26 and the driving motor 25 belong to two transmission systems and do not interfere with each other.

[0045] A control device 2 is arranged outside the frame 1 to control the above structure. The control device 2 adopts a PLC controller. The control device 2 controls the above drive structure and monitors the above sensing structure at the same time, so that the utility model can achieve high automation and reduce the workload of the staff.

[0046] When the utility model is used, the staff places the magnet in the magnet separation jig 4, which is a prior art and can separate the magnet into an S pole and an N pole. After the magnet separation jig 4 has separated the magnet, the separated magnet is located in the magnet receiving groove 6. Under the action of the magnet front and rear cylinders 12 and the magnet lifting cylinder 11, the air nozzle of the vacuum cylinder 9 is located at the magnet receiving groove 6.

[0047] When the air nozzle of the vacuum cylinder 9 is aligned with the magnet receiving groove 6, the magnet pushing cylinder 5 pushes the separated magnet through the push rod 7, so that the separated magnet is located directly below the air nozzle of the vacuum cylinder 9. At the same time, the magnet is located in the arc groove 10. Under the action of the arc groove 10, the magnet is compressed, and the vacuum cylinder 9 is started to adsorb the magnet in the arc groove 10.

[0048] When the magnet is vacuum-absorbed, the drive motor 25 in the drive structure drives the connecting plate 8 to move horizontally, and the magnet front and rear cylinders 12 and the magnet lifting cylinder 11 adjust the height and front and rear position of the magnet;

[0049] While the magnet is being separated by the magnet separation jig, the staff fixes one end of the iron core on the rotating shaft 13, and the outer edge of the iron core is supported and limited by the auxiliary groove 18 on the support plate 17. The staff starts the push cylinder 14, and under the action of the push cylinder 14, the ejector pin 15 cooperates with the rotating shaft 13 to position and fix the iron core. After the iron core is fixed, the material auxiliary cylinder 16 drives the support plate 17 to move downward, so that the support plate 17 is separated from the outer edge of the iron core;

[0050] The glue coating structure approaches the fixed iron core under the action of the stepping motor 26 and the transmission belt 27. When the positioning sensor 22 recognizes and matches the positioning block on the iron core, the glue injector 23 is pressurized under the action of the upper and lower cylinders 21, so that the glue flows out from the outlet of the glue injector 23. Under the action of the stepping motor 26 and the transmission belt 27, the glue injector 23 is coated along the axis direction of the iron core.

[0051] After the coating is completed, the rotating shaft 13 drives the iron core to rotate 90 degrees for the glue coating of the next workstation. After the glue coating is completed, the glue coating structure returns to its initial position and will not interfere with the magnet transfer structure. At this time, the vacuum cylinder 9 drives the magnet thereon to move to the top of the iron core, and moves downward to bond the magnet to the outer edge surface of the iron core. After multiple actions, multiple S poles and N poles are adhered to the outer edge surface of the iron core.

[0052] The utility model utilizes a vacuum cylinder and an arc groove arranged at the air nozzle to adsorb the separated magnets, and simultaneously utilizes a driving motor, a magnet lifting cylinder, and a magnet front and rear cylinder to move the position of the magnet, thereby automatically bonding the magnet to the iron core;

[0053] The utility model is provided with a glue coating structure, in which the glue coating device and the outer edge surface of the iron core are at an angle of 30-45 degrees. The above angle can make the glue flow out of the glue coating device more evenly on the one hand, and on the other hand, the glue outlet of the glue coating device can fit with the outer edge surface of the iron core with a larger contact area;

[0054] The utility model utilizes a photoelectric sensor and a fan-shaped plate to perform closed-loop control on the rotation angle of the rotating shaft, so that the rotating shaft drives the iron core to rotate to a suitable angle accurately.
