Technical Field
[0001] This utility model relates to the field of magnetic steel detection technology, and in particular to a planar detection and arrangement device for irregularly shaped magnetic steel. Background Technology
[0002] Neodymium iron boron magnets are the magnetic materials with the strongest permanent magnetism to date. They are characterized by small size, light weight and strong magnetism, and have high magnetic properties. They have been widely used in transportation, machinery, medical and other industries.
[0003] In practical applications, neodymium iron boron (NdFeB) magnets come in a variety of shapes, including round pieces, rings, square pieces, fan shapes, tile shapes, groove shapes, and irregular shapes. All NdFeB magnets must pass a full inspection by inspectors before being shipped. A qualified appearance must be free of chips, cracks, dirt, etc. For certain complex-shaped magnets, the full inspection requires inspectors to visually inspect the contours using tweezers, rearranging the magnets on a flat surface so that all flat surfaces are facing upwards. This arrangement is considered the correct inspection state. However, visual inspection cannot guarantee perfect alignment, leading to the risk of missed inspections. Repeated checks are necessary, and with large quantities of magnets, this process is time-consuming and labor-intensive, failing to meet daily inspection efficiency.
[0004] Therefore, it is necessary to develop a planar detection and arrangement device for irregularly shaped magnets to solve the above problems. Utility Model Content

[0008] In some embodiments, the contoured hole further includes three connecting walls, and adjacent contoured walls are connected by corresponding connecting walls.
[0009] In some embodiments, both the contoured vertical wall and the connecting vertical wall have a chamfer or rounded corner at one end corresponding to the opening of the contoured hole.

[0012] In some embodiments, the depth of the contoured hole is equal to the height of the first planar end of the irregularly shaped magnet from the second planar end.
[0013] In some embodiments, both the arrangement plate and the cover plate are 3D printed using photosensitive resin.

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.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0022] This utility model provides a planar detection and arrangement device for irregularly shaped magnets, such as... Figures 1 to 7 As shown, the system includes an arrangement plate 1 and a cover plate 2. The arrangement plate 1 has multiple contoured holes 11 for embedding irregularly shaped magnets 3, each contoured hole 11 being recessed inward from the surface of the arrangement plate 1. The irregularly shaped magnet 3 includes a first planar end 31, a second planar end 32, and multiple sidewalls connecting the first planar end 31 and the second planar end 32. The inner wall shape of the contoured hole 11 is configured to match or contour the shape of the multiple sidewalls of the irregularly shaped magnet 3. In a first detection state, the bottom 113 of the contoured hole 11 contacts the first planar end 31 of the irregularly shaped magnet 3, and the inner wall of the contoured hole 11 is opposite to the multiple sidewalls of the irregularly shaped magnet 3, with the surface of the second planar end being the surface to be inspected. In a second detection state, the cover plate 2 can be engaged with the side of the arrangement plate 1 where the contoured holes 11 are arranged to support the inverted irregularly shaped magnet 3, with the surface of the first planar end being the surface to be inspected.
[0023] In some embodiments, such as Figures 5 to 7 As shown, the horizontal cross-section of the contour hole 11 is triangular, and the inner wall of the contour hole 11 includes three contour vertical walls 111. The irregular magnet 3 includes two arc-shaped side walls 33 and a flat side wall 34. In the first detection state, the three contour vertical walls 111 are respectively arranged opposite to the two arc-shaped side walls 33 and the flat side walls 34 and have a preset gap. In the second detection state, under the bearing action of the cover plate 2, all irregular magnets 3 are upside down and can be dislodged from the contour hole 11 on the arrangement plate 1.
[0024] In some embodiments, such as Figure 7 As shown, the contour hole 11 also includes three connecting walls 112, and adjacent contour walls 111 are connected by corresponding connecting walls 112.
[0025] In some embodiments, such as Figure 7 As shown, both the contoured vertical wall 111 and the connecting vertical wall 112 have chamfers or rounded corners at one end of the corresponding contoured hole 11 opening position.
[0026] In some embodiments, such as Figure 2 As shown, the arrangement plate 1 has multiple rows of contour hole arrays, each row of contour hole array includes multiple contour holes 11; the tips of the triangular structures of the multiple contour holes 11 in the same row of contour hole arrays are oriented in the same direction and the bases opposite to the tips are arranged parallel; the tips of the triangular structures of the multiple contour holes 11 in two adjacent rows of contour hole arrays are oriented in opposite directions and the bases opposite to the tips are arranged in a staggered parallel manner.
[0027] In some embodiments, such as Figure 1 and Figure 4 As shown, the end of the arranging plate 1 is provided with a boss 21, and the end of the cover plate 2 is provided with a recess 12 that matches the boss 21; or the end of the arranging plate 1 is provided with a recess 12, and the end of the cover plate 2 is provided with a boss 21 that matches the recess 12.
[0028] In some embodiments, the depth dimension of the contour hole 11 is equal to the height dimension of the distance between the first planar end 31 and the second planar end 32 of the irregular magnet 3.
[0029] In some embodiments, both the arrangement plate 1 and the cover plate 2 are 3D printed using photosensitive resin.
[0030] In some embodiments, the height of the boss 21 is equal to the depth of the recess 12; the boss 21 can gradually engage with the recess 12 from one side along the length of the recess 12 to the other side, and the entrance end of the recess 12 in the length direction is provided with a chamfer or rounded corner.
[0031] In some embodiments, the cover plate 2 and the arrangement plate 1 are in a snap-fit state with their opposite surfaces touching.
[0032] In use, the irregularly shaped magnet plane detection and arrangement device of this utility model first arranges irregularly shaped magnets 3 above the shaped holes 11 on the arrangement plate 1. By swinging the arrangement plate, the irregularly shaped magnets 3 move repeatedly on the surface of the arrangement plate 1. Most of the irregularly shaped magnets 3 freely enter the space of the shaped holes 11. At this time, the irregularly shaped magnets 3 are in a state where their planes are all facing upwards. Since the space of the shaped holes 11 is shaped to resemble the irregularly shaped magnets 3 and its size is slightly larger than the outer contour size of the irregularly shaped magnets 3, magnets in other positions cannot completely enter the space of the shaped holes. The inspector removes the irregularly shaped magnets 3 that have not entered the space and performs a full visual inspection of the plane of the irregularly shaped magnets 3, screening out unqualified products containing chips, cracks, dirt, etc. After the inspection is completed, the cover plate 2 is combined with the arrangement plate 1. After combination, the outer contours of the two are in a state of overlap. At this time, the arrangement plate 1 is below and the cover plate 2 is above, and there is no obvious gap between the two plates, which means that there are no impurities or residual magnets. Otherwise, it will affect the flipping operation. The two combined plates are flipped 180 degrees at the same time, with the cover plate 2 at the bottom and the arrangement plate 1 at the top. Then, the arrangement plate 1 is removed vertically to prevent the irregular magnet 3 from tipping over. The irregular magnet 3 will fall neatly in the area of the cover plate 2, allowing the inspectors to perform a full visual inspection of this other side of the plane.
[0033] Inspectors use the arranging plate 1 to arrange the irregularly shaped magnets 3. The operation is simple, and after arrangement, the irregularly shaped magnets 3 have a consistent posture. With the help of the cover plate 2, the inspection is carried out by flipping the plate, which allows for full inspection of both sides of the magnets. This method is simple, effective, low-cost, and easy to popularize, and can meet the needs of batch full inspection of irregularly shaped magnets 3.
[0034] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
