Description

Technical Field

[0001] This utility model relates to the field of magnetization technology, and in particular to a permanent magnet magnetization device. Background Technology

[0002] Permanent magnets, due to their excellent magnetic properties, have been widely used in various fields, including new energy vehicles, precision electronic equipment, and medical devices. Permanent magnets made from permanent magnet materials need to be magnetized, which requires a magnetizing magnetic field, provided by a magnetizer. Patent application number 202311500925.8 discloses an energy-saving automatic permanent magnet magnetizer and its magnetizing process, which uses a power cylinder to drive a piston rod to extend and retract, controlling the approach and departure of the permanent magnet, and coordinating with the opening and closing of a baffle to achieve magnetization of the permanent magnet material.

[0003] However, through in-depth research and practical application, the inventors discovered significant shortcomings in the workflow design of this magnetizer. The material loading and unloading processes must be carried out when the material loading groove is unobstructed, resulting in an intermittent "magnetizing-pause-loading / unloading-remagnetizing" working mode. During magnetization, operators can only wait for the magnetization to finish and cannot simultaneously perform material loading or unloading operations. This leads to a considerable period of idle waiting within each magnetization cycle, thus requiring improvement in work efficiency.

[0004] Therefore, it is essential to develop a permanent magnet magnetization device that can simultaneously magnetize and load / unload materials to improve work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a permanent magnet magnetizing device that improves upon existing magnetizers to achieve simultaneous magnetizing and material handling, thereby increasing work efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a permanent magnet charging device, including a protective box, on which two charging components are slidably connected. A transmission component for driving the two charging components to move towards or away from each other is installed on the protective box. The device also includes:

[0008] A rotating disk is rotatably connected to the protective box. Its rotation axis is parallel to the sliding direction of the magnetizing component. Its bottom end is located between the two magnetizing components, and its top end protrudes out of the protective box. A number of placement components for placing permanent magnets are evenly distributed around its circumference.

[0009] An anti-detachment component is disposed on the periphery of the rotating disk and fixedly connected to the protective box; the top of the anti-detachment component is provided with a clearance opening for the permanent magnet to enter and exit the placement component;

[0010] A drive component is mounted on the protective box and is capable of driving the rotating disk to rotate.

[0011] Optionally, the number of placement components is 2, 4, or 6.

[0012] Optionally, the placement assembly includes accommodating grooves evenly distributed around the circumference of the rotating disk, and an accommodating barrel is detachably connected to the accommodating groove, the inner cavity of the accommodating barrel being adapted to the permanent magnet.

[0013] Optionally, the anti-detachment component includes a ring body, which is sleeved around the circumference of the rotating disk, and the clearance opening is formed at the top of the ring body.

[0014] Optionally, a plurality of rotating shafts are evenly distributed around the inner wall of the ring, and the rotating shafts are tangent to the circumferential side surface of the rotating disk.

[0015] Optionally, both the rotating disk and the placement assembly are made of non-ferromagnetic materials.

[0016] Optionally, support shafts are fixed on both sides of the rotating disk, and the support shafts are rotatably connected to the protective box.

[0017] Optionally, the driving component is a servo motor, and the output shaft of the servo motor is connected to one end of any of the support shafts via a key.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0019] By coordinating the operation of the rotating disk, placement components, anti-detachment components, drive components, transmission components, and magnetization components, magnetization and material handling are synchronized. Taking two placement components as an example, while the permanent magnet in one placement component is being magnetized, the other placement component can perform material handling operations without waiting for magnetization to finish, significantly reducing equipment downtime and improving work efficiency compared to existing magnetization equipment.

Detailed Implementation

[0027] The core of this invention is to provide a permanent magnet magnetizing device that improves upon existing magnetizers to achieve simultaneous magnetizing and material handling, thereby improving work efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In a specific embodiment of this utility model, a protective box 100 is included, on which two magnetizing components are slidably connected. A transmission component for driving the two magnetizing components to move towards or away from each other is installed on the protective box 100. The above belongs to the prior art; for details, please refer to the relevant functional content in patent application number 202311500925.8. This application removes the cam-driven baffle unit and cam plate from the aforementioned patent and improves upon the remaining structure.

[0031] This utility model also includes:

[0032] The rotating disk 200 is rotatably connected to the protective box 100. Its rotation axis is parallel to the sliding direction of the magnetizing component. Its bottom end is located between the two magnetizing components, and its top end protrudes out of the protective box 100. A number of placement components for placing permanent magnets are evenly distributed around its circumference.

[0033] An anti-detachment component is installed around the rotating disk 200 and fixedly connected to the protective box 100; the top of the anti-detachment component is provided with a clearance opening 300 for the permanent magnet to enter and exit the placement component; the anti-detachment component can prevent the permanent magnet from falling off during the rotation of the rotating disk 200.

[0034] The drive component 400 is mounted on the protective box 100 and is capable of driving the rotating disk 200 to rotate.

[0035] In a specific embodiment of this utility model, the number of placement components is an even number, such as 2, 4 or 6, so as to ensure that during the magnetization process of the permanent magnet in the placement component at the bottom of the rotating disk 200, the placement component at the top of the rotating disk 200 can be aligned with the clearance opening 300, so that the permanent magnet can enter and exit the placement component from the clearance opening 300, thereby realizing the simultaneous magnetization and material handling.

[0036] When magnetizing a permanent magnet with low coercivity, two placement components can be set. When the permanent magnet in the bottom placement component is being magnetized, the magnetized permanent magnet will be located at the top of the rotating disk 200, so that it can be removed.

[0037] In a specific embodiment of this utility model, the placement component includes accommodating grooves evenly distributed around the circumference of the rotating disk 200, and an accommodating barrel 500 is detachably connected to the accommodating groove (e.g., the accommodating groove is detachably connected to the accommodating barrel 500 by screws), so that the accommodating barrel 500 can be replaced; the inner cavity of the accommodating barrel 500 is adapted to the permanent magnet.

[0038] In a specific embodiment of this utility model, the anti-detachment component includes a ring 600, which is sleeved around the rotating disk 200, and an clearance opening 300 is formed at the top of the ring 600. It should be noted that connecting parts are fixed on both sides of the ring 600, and the connecting parts are fixedly connected to the protective box 100 by bolts.

[0039] In a specific embodiment of this utility model, a plurality of rotating shafts 700 are evenly distributed around the inner wall of the ring 600, and the rotating shafts 700 are tangent to the circumferential side of the rotating disk 200. Specifically, two arc-shaped plates 610 are welded or integrally formed on the inner wall of the ring 600, and the rotating shafts 700 are located between the two arc-shaped plates 610. Self-lubricating bearings 710, such as graphite copper bushing bearings, are installed in the blind holes at both ends of the rotating shafts 700. The arc-shaped plates 610 are equipped with through holes, and a shaft 611 and a hollow elastic retaining ring 612 for limiting one end of the shaft 611 are installed in the through holes. The other end of the shaft 611 protrudes from the through holes and is rotatably connected to the central hole of the self-lubricating bearing 710.

[0040] The rotating shaft 700 is designed to prevent the permanent magnet from directly contacting the ring 600 during the rotation of the rotating disk 200 and the container 500, thereby reducing friction and ensuring smooth rotation.

[0041] In a specific embodiment of this utility model, both the rotating disk 200 and the placement component are made of non-ferromagnetic materials, such as copper, aluminum, and aluminum alloys.

[0042] In a specific embodiment of this utility model, support shafts 800 are fixed on both sides of the rotating disk 200, and the support shafts 800 are rotatably connected to the protective box 100 through bearing seats.

[0043] In one specific embodiment of this utility model, the driving component 400 is a servo motor, and the output shaft of the servo motor is connected to one end of any support shaft 800 via a key. Both the servo motor and the power cylinder 900 in the transmission assembly are controlled by an externally configured controller.

[0044] The working process of this utility model's permanent magnet charging device, taking the setting of two placement components as an example (the principle of the remaining placement components is the same, except that the angle of rotation of the rotating disk 200 is different each time, and the angle of rotation of the rotating disk 200 each time is: 360° divided by the number of placement components):

[0045] In the initial operation, the equipment is started, and the transmission component drives the two magnetizing components to move in opposite directions, increasing the distance between the magnetizing components. The operator then places the permanent magnet into the placement component (accommodating bucket 500) that is aligned with the top of the rotating disk 200 and the clearance opening 300.

[0046] Simultaneously, the transmission component drives the magnetizing components to move towards each other, while the drive component 400 (servo motor) drives the rotating disk 200 to rotate, causing the placement component containing the permanent magnet to rotate between the two magnetizing components. At this time, the magnetizing components magnetize the permanent magnet. During magnetization, the placement component at the top of the rotating disk 200 is aligned with the clearance opening 300, and the operator can place the permanent magnet to be magnetized into the receiving container 500.

[0047] The cycle continues. After magnetization is completed, the transmission component drives the magnetization component to move in opposite directions. At the same time, the drive component 400 drives the rotating disk 200 to rotate again, rotating the magnetized permanent magnet to the top for removal. Meanwhile, the newly placed permanent magnet to be magnetized will rotate to the bottom for magnetization. This cycle continues.

[0048] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

[0049] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
