Description

Technical Field

[0001] The utility model relates to the technical field of magnetic ring production, in particular to a full-automatic magnetic ring magnetizing device. Background Art

[0002] A magnetic ring is a ring-shaped magnetic conductor and a key component in electronic and automation components. For example, the magnetic ring on a motor rotor provides a stable magnetic field. Magnetic ring production typically involves processing magnetic ring material (such as ferrite or other alloys) into a magnetic ring blank (hereinafter referred to as the blank). This blank is then magnetized to create a permanent magnetic ring. Typically, a magnetizer is used for magnetization. This relatively simple structure consists of an extremely strong electromagnet equipped with iron blocks of various shapes as additional poles to form a closed magnetic circuit with the magnetized object. Magnetization is accomplished by arranging the additional poles and the magnetic ring blank, applying the excitation current, and the process is completed instantly.

[0003] Existing magnetizing devices first place the magnetic ring blank in a magnetizing base, then transfer the base to a magnetizer to complete magnetization. After magnetization is complete, a lifting mechanism ejects the magnetic ring from the base, allowing workers to remove the ring and replace it with a new magnetic ring blank. However, this loading and unloading method requires the base to remain stationary during loading and unloading, resulting in a long magnetization interval, which reduces the production efficiency of magnetic rings. Therefore, a fully automatic magnetic ring magnetizing device was proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fully automatic magnetic ring magnetizing device to solve the above problems.

Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] Reference Figures 1 to 4 The embodiment of the present invention provides a fully automatic magnetic ring magnetizing device, comprising a base 10, a magnetizer 20, a conveying mechanism 30, a loading mechanism 40, and an unloading mechanism 50. The base 10 is disc-shaped, and the magnetizer 20 and the loading mechanism 40 are both arranged on the base 10 and are both located near the edge of the upper surface of the base 10. The connecting line of the magnetizer 20 and the loading mechanism 40 is on a straight line where a symmetry axis of the base 10 is located. The conveying mechanism 30 includes a magnetizing seat 31 arranged on the base 10, and the magnetizing seat 31 can periodically pass through the magnetizer 20 and the loading mechanism 40. Specifically, the magnetizing seat 31 can perform circular motion, thereby periodically passing through the magnetizer 20 and the loading mechanism 40. The magnetizing seat 31 is provided with a blank mounting position. Specifically, the magnetizing seat 31 is annular, and the center hole is the blank mounting position. The diameter of the center hole is slightly larger than the outer diameter of the blank.

[0034] The feeding mechanism 40 includes a feeding plate 41 mounted on the base 10, a barrel 42 mounted on the feeding plate 41, and a pusher 43. The barrel 42 is vertically mounted, with a gap between its lower end and the feeding plate 41. Optionally, the distance between the lower end of the barrel 42 and the feeding plate 41 is greater than the thickness of a single stock but less than twice the thickness of a single stock. When the barrel 42 is loaded with stock, the stock in the barrel 42 nears the opening of the feeding plate 41 and falls onto the feeding plate 41. A feeding hole 44 is provided on the feeding plate 41. When the magnetizing base 31 moves onto the feeding mechanism 40, the magnetizing base 31 is positioned below the feeding plate 41, with the feeding hole 44 aligned with the center hole of the magnetizing base 31. The diameter of the feeding hole 44 is equal to the diameter of the center hole of the magnetizing base 31. A loading hole 44 is provided at one end of the loading plate 41, and a pusher 43 is provided at the end of the loading plate 41 away from the loading hole 44. The barrel 42 is located above and between the loading hole 44 and the pusher 43. The pusher 43 is a telescopic cylinder, the telescopic rod of which pushes the blank that has fallen onto the loading plate 41 toward the loading hole 44, allowing the blank to fall through the loading hole 44 into the center hole of the magnetizing seat 31, i.e., into the blank mounting position.

[0035] The blanking mechanism 50 includes a baffle 51 disposed on the lower end surface of the blank mounting position and a lever 52 disposed on the base 10. When the blank falls into the center hole of the magnetizing seat 31, if there is no support, the blank will fall out of the center hole. The baffle 51 closes the lower opening of the center hole to prevent the blank from falling out of the center hole. The baffle 51 can rotate about a first rotation axis. After the magnetizer 20 magnetizes the blank to form a magnetic ring, the baffle 51 is rotated to open the lower opening of the center hole. The magnetic ring falls outside the magnetizing seat 31 under the action of gravity. The lever 52 is used to move the baffle 51 to rotate the baffle 51, thereby opening the lower opening of the center hole.

[0036] Specifically, during magnetization, the blanks are stacked in the barrel 42. When the magnetizing seat 31 moves onto the loading mechanism 40, the pusher 43 pushes the blanks to the loading hole 44, and the blanks enter the center hole of the magnetizing seat 31 through the loading hole 44. Then, the magnetizing seat 31 moves onto the magnetizer 20, and the magnetizer 20 magnetizes the blanks to form a magnetic ring with permanent magnetism. Finally, the magnetizing seat 31 continues to move, and when it passes the lever 52, the lever 52 moves the baffle 51, causing the baffle 51 to rotate to open the lower orifice of the center hole, and the magnetic ring falls to the outside of the magnetizing seat 31, completing the unloading.

[0037] Furthermore, the conveying mechanism 30 also includes a drive motor 32 embedded in the base 10. The base 10 is disc-shaped, and the drive motor 32 is positioned at the center of the base 10. The output shaft of the drive motor 32 is aligned with the axis of the base 10. A mounting seat 33 is provided on the output shaft of the drive motor 32, the lower surface of which is higher than the upper surface of the base 10. Multiple connecting rods 34 are mounted at equal angles to the side of the mounting seat 33, and a magnetizing seat 31 is positioned at the end of the connecting rods 34 away from the mounting seat 33. When the drive motor 32 is operating, the output shaft of the drive motor 32 drives the mounting seat 33 to rotate, thereby driving the magnetizing seat 31 in a circular motion. In this embodiment, the magnetizer 20 is open on three sides. Specifically, the side of the magnetizer 20 adjacent to the mounting seat 33 and the two adjacent sides are open. When the magnetizing seat 31 moves in a circular motion, the magnetizing seat 31 can enter the magnetizer 20.

[0038] Furthermore, the loading mechanism 40 includes a support column 45, on which a loading plate 41 is mounted. The longitudinal axis of the loading plate 41 is coplanar with an axis of symmetry of the base 10. A rail 46 is provided on the loading plate 41, one end of which is connected to the loading hole 44 and the other end is located below the barrel 42. The stock in the barrel 42 can fall onto the rail 46. Optionally, the width of the rail 46 is equal to the diameter of the stock; the distance between the bottom surface of the rail 46 and the lower end of the barrel 42 is greater than the thickness of a single stock but less than twice the thickness of a single stock. The barrel 42 is suspended above the base 10 by a support rod 47. Optionally, the barrel 42 and the support rod 47 are detachably connected. Once all the stock in the barrel 42 has been loaded onto the magnetizing base 31, the fully loaded barrel 42 can be replaced with the support rod 47, allowing for quick replenishment of the stock.

[0039] Furthermore, the unloading mechanism 50 includes a torque driver 53 disposed on one side of the magnetizing base 31. Optionally, the torque driver 53 is disposed on the end of the connecting rod 34 near the magnetizing base 31. The torque driver 53 includes a body 531 and a rotating shaft 532 rotatably connected to the body 531. The rotating shaft 532 serves as a first rotation axis. The baffle 51 is disposed on the rotating shaft 532. When the rotating shaft 532 rotates, the baffle 51 rotates about the rotating shaft 532.

[0040] A torsion spring (not shown) is disposed within the body 531, and the rotating shaft 532 is mounted on the torsion spring. Specifically, the portion of the rotating shaft 532 embedded within the body 531 is a hollow cylinder, and the torsion spring is sleeved within the rotating shaft 532. One end of the torsion spring is fixedly connected to the body 531, and the other end is connected to the inner wall of the rotating shaft 532. When the rotating shaft 532 rotates, the rotating shaft 532 is subjected to a restoring force provided by the torsion spring. That is, when the lever 52 moves the baffle 51 to rotate it, and the force exerted by the lever 52 on the baffle 51 reaches zero, the baffle 51, under the restoring force of the rotating shaft 532, will rotate back to its pre-rotation state, thereby resealing the lower opening of the center hole of the magnetizing seat 31.

[0041] An auxiliary rod 54 is provided on the side of the baffle 51 away from the rotating shaft 532, corresponding to the lever 52. The lever 52 is fixed to the base 10. When the lever 52 moves the baffle 51, it remains stationary. As the magnetizing seat 31 moves in a circular motion, the baffle 51 is moved by the lever 52. After the baffle 51 and the lever 52 come into contact, the distance between the lever 52 and the rotating shaft 532 increases. The auxiliary rod 54 increases the rotation angle of the lever 52 to move the baffle 51, thereby allowing the baffle 51 to fully open the center hole of the magnetizing seat 31.

[0042] Optionally, the lever 52 is arranged upstream of the loading mechanism 40 along the moving direction of the magnetizing seat 31, so that when the magnetizing seat 31 enters the loading mechanism 40 again, there is no magnetic ring on the magnetizing seat 31; a storage box 60 is provided on the base 10, and the storage box 60 is arranged downstream of the lever 52 along the moving direction of the magnetizing seat 31, that is, after the magnetic ring falls outside the magnetizing seat 31, it falls into the storage box 60.

[0043] Optionally, a supporting foot 11 is provided on the lower end surface of the base 10 .

[0044] The utility model discloses a fully automatic magnetic ring magnetizing device, and the specific embodiment is as follows: during magnetization, the magnetizing seat 31 periodically passes through the feeding mechanism 40 and the magnetizing machine 20 in sequence. In the feeding mechanism 40, the blank is stacked in the barrel 42. Under the action of gravity, the blank at one end of the barrel 42 near the feeding plate 41 falls into the feeding plate 41. The pushing member 43 pushes the blank on the feeding plate 41. At this time, the magnetizing seat 31 moves to the bottom of the feeding plate 41, and the blank falls into the blank mounting position on the magnetizing seat 31 through the feeding hole 44. After the loading is completed, the magnetizing seat 31 moves to the magnetizing machine 20, and the magnetizing machine 20 magnetizes the blank. After the magnetization is completed, the magnetizing seat 31 passes through the lever 52 during the movement to the feeding mechanism 40. The lever 52 shifts the baffle 51, causing the baffle 51 to rotate outside the blank mounting position, and the magnetic ring falls outside the magnetizing seat 31, so that the magnetic ring can be removed. The fully automatic magnetizing device provided by the utility model pushes the blanks to the magnetizing seat 31 one by one by the pushing member 43, and then the baffle 51 is pushed out of the blank installation position by the shifting rod 52 to allow the magnetic ring to fall under the action of gravity, thereby completing the automatic loading and unloading of the magnetizing device without unnecessary intermittent time, thereby greatly improving the efficiency of magnetic ring production.

Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein.
